BRACKNELL has many pleasant landmarks to its name, with several green spaces and picturesque spots often used as filming locations, so it's easy to forget that the town also homes some of the most dangerous psychiatric patients in the country.

In the centre of Crowthorne sits Broadmoor Hospital - the oldest of the three high-security psychiatric hospitals in England.

From the Stockwell Strangler to the Yorkshire Ripper, the hospital has seen some terrifyingly infamous people walk through its doors.

Founded in 1863, Broadmoor houses about 210 patients today, all of whom have been men since the female service closed in 2007.

According to Wikipedia, the average stay is six years, but this figure is skewed by a few patients who have stayed for more than 30 years; most patients stay for considerably less time.

The famous criminal hospital is still very much in use today, with one of the latest patients to be committed being the teenager who threw a six-year-old boy off a 200ft Tate Modern balcony in August this year.

Jonty Bravery, 18, said he did it because he wanted to be 'famous.'

We have taken a look at some of the most dangerous people to have resided in Broadmoor, and compiled a list of the more notable people you may have forgotten were living in the Bracknell facility.

Below are just five of the many Broadmoor convicts you have probably heard of, but will definitely find interesting - if a little scary.

1) Ronald Kray

Twin brothers Ronald 'Ronnie' Kray and Reginald 'Reggie' Kray were criminals who operated in organised crime in the East End of London during the 1950s and 60s.

With their gang, known as "The Firm", the Krays were involved in murder, armed robbery, arson, protection rackets and assaults.

They were also involved in violence, including the torture and murders of Jack 'The Hat' McVitie and George Cornell.

As West End nightclub owners, the Kray twins mixed with politicians and prominent entertainers such as Diana Dors, Frank Sinatra and Judy Garland.

They became celebrities themselves, were photographed by David Bailey and interviewed on television.

Ronnie began to show signs of mental illness, and was later diagnosed with paranoid schizophrenia.

Apparently he would refuse to eat, shave only half of his face and suffer wild and violent mood swings.

After several other criminal incidents, Ronnie was eventually certified insane and lived the remainder of his life in Broadmoor, dying on 17 March 1995 of a heart attack, aged 61.

Reggie was released from prison on compassionate grounds in August 2000, a few weeks before his death from cancer.

2) Peter Sutcliffe: 'The Yorkshire Ripper'

Peter William Sutcliffe, also known as Peter William Coonan, was dubbed the "Yorkshire Ripper" by the press.

On May 22, 1981, Sutcliffe was convicted of murdering 13 women and attempting to murder seven others.

He is serving 20 concurrent sentences of life imprisonment, which was increased to a whole life order in 2010.

All except two of his murders took place in West Yorkshire; the others were in Manchester.

He frequented prostitutes as a young man and it has been speculated that a bad experience with one (during which he was allegedly conned out of money) helped fuel his violent hatred against women.

In 1981, Sutcliffe was stopped by the police with a 24 year old prostitute.

At Dewsbury he was questioned in relation to the Yorkshire Ripper case as he matched so many of the physical characteristics known.

The next day police returned to the scene of the arrest and discovered a knife, hammer and rope he discarded when he briefly slipped away from police during the arrest.

In January 1981, following police questioning, Sutcliffe suddenly declared he was the Ripper.

He later calmly described his many attacks, and claimed God told him to murder the women.

3) Robert Napper

Robert Clive Napper is a convicted British murderer and rapist who was remanded in Broadmoor Hospital indefinitely on December 18, 2008 for the manslaughter of Rachel Nickell.

Napper’s convictions include an offence with an air-gun, stabbing a young mother 49 times in front of her two year-old son, killing then sexually assaulting a woman before smothering her four-year-old daughter, and two rapes.

However, it is believed he is the ‘Green Chain Rapist’ who carried out at least 70 savage attacks across south-east London over a four-year period ending in 1994.

From the time of his first Old Bailey trial, he has been held at Broadmoor.

4) David Copeland

David John Copeland became known as the “London Nail Bomber,” after a 13-day bombing campaign in April 1999 aimed at London’s black, Bangladeshi and gay communities.

The bombs killed three, including a pregnant woman, and injured 129, four of whom lost limbs.

On 2 May 1999, the Metropolitan Police Anti-Terrorist Branch charged 22-year-old David Copeland with murder.

Copeland was a Neo-Nazi militant and a former member of two far-right political groups, the British National Party and then the National Socialist Movement.

Copeland's mental state was assessed at Broadmoor Hospital. He was diagnosed by five psychiatrists as having paranoid schizophrenia, while one diagnosed a personality disorder not serious enough to avoid a charge of murder.

There was no dispute that he was mentally ill, but the extent of this, and whether he was unable to take responsibility for his actions, became a matter of contention. At the Old Bailey, Copeland's plea of guilty to manslaughter on the grounds of diminished responsibility was not accepted by the prosecution or jury.

He was convicted of murder in 2000 and given six concurrent life sentences.

5) Kenneth Erskine: 'The Stockwell Strangler'

During 1986, Erskine murdered at least seven elderly people, breaking into their homes and strangling them.

They were usually sexually assaulted.

Erskine was 24 years old when he committed the crimes, but had the mental age of a 12-year-old. Police suspected Erskine of four others murders but Erskine has never been charged with any of these murders. Erskine was sentenced to life imprisonment with a recommended minimum term of 40 years, but has since been found to be suffering from mental disorder within the meaning of the Mental Health Act 1983, and is therefore now held at Broadmoor.

These are just five of many shocking cases of those who ended up in the tightly-guarded Bracknell hospital.

Some have now died, while others will live the remainder of their lives at Broadmoor.
