NOTORIOUS prisoner Charles Bronson has been subject to some ‘brutal and unacceptable’ treatment behind bars, a psychologist told his parole hearing.

The second day of Bronson’s parole review heard one of the UK’s longest serving prisoners holds ‘anti-authoritarian views’ and is ‘suspicious’ of the motives of others.

Three parole judges – who have not been publicly named – are considering his case at HMP Woodhill in Milton Keynes, Buckinghamshire, while members of the press and public watch the proceedings on a live stream from the Royal Courts of Justice in central London.

An independent psychologist employed by Bronson’s legal team told the hearing on Wednesday: “He feels like the whole system is about humiliating and degrading him.”

Wearing a black t-shirt with white writing on it, and his trademark dark, round glasses, Bronson could be seen rocking his chair backwards and forwards as the psychologist gave evidence.

She said the 70-year-old has mild symptoms of post-traumatic stress disorder, partly due to some ‘brutal and unacceptable treatment’ while in the prison system.

Bronson – whose real name is Michael Peterson – has previously been diagnosed with anti-social personality disorder, is ‘naturally somewhat suspicious of other people’s motives’ and holds ‘anti-authoritarian views’, the psychologist added.

Once dubbed one of Britain’s most violent offenders, Bronson has spent most of the past 48 years behind bars, apart from two brief periods of freedom during which he reoffended, for a string of thefts, firearms and violent offences, including 11 hostage takings in nine different sieges. Victims included governors, doctors, staff and, on one occasion, his own solicitor.

He was handed a discretionary life sentence with a minimum term of four years in 2000 for taking a prison teacher at HMP Hull hostage for 44 hours. Since then, the Parole Board has repeatedly refused to direct his release.

Bronson – who changed his surname to Salvador in 2014 – is the second inmate in UK legal history to have his case heard in public after rules changed last year in a bid to remove the secrecy around the process.

The third and final day of the proceedings will take place behind closed doors on Friday so confidential details can be discussed.

Bronson previously told the parole board: “It’s no secret I have had more porridge than Goldilocks and the Three Bears, and I’m sick of it. I’ve had enough of it, I want to go home”.

The parole board will consider whether he should remain behind bars after the hearing, with a decision due at a later date.
