Naked Charles Bronson squares up to army of 15 prison guards in newly emerged footage

Newly emerged footage of Britain's most notorious prisoner shows the moment Charles Bronson takes on a small army of 15 police officers.

The bizarre scenes offer an insight to just some of what Bronson got up to behind bars while earning himself the title of one of the UK's longest-serving prisoners. See for yourself below.

In just a matter of days, Bronson will be the focus of a public Parole Board hearing in which a panel will determine whether the 70-year-old inmate is fit for release.

Ultimately the decision will be down to those on the board, but a Channel 4 documentary titled Bronson: Fit to be Free? attempts to answer that same question.

The documentary, which is available to stream now, features interviews with Bronson as well as some of the people closest to him, the victims of his crimes and footage from his life.

Bronson's efforts to take on multiple guards is just one of the insights given in the documentary, and shows the moment Bronson provoked the officers by wiggling his naked body around in the corridor while the officers grouped together facing him.

The prisoner didn't look phased as the officers geared up ready to take him down and instead continued to wiggle his hips at them, only stopping when he was hit with purple tear gas.

Bronson fell to the floor and was overpowered by the officers, while the dramatic sounds of 'Zadok the Priest' by Handel plays out over the top of the scene.

As part of his interviews in the doc, Bronson describes arriving high-security HMP Parkhurst in the 1970s after being convicted of armed robbery.

There, he met the infamous Kray twins and the men behind the Great Train Robbery, while at the same time earning a reputation as a violent inmate.

During his time behind bars, Bronson has carried out a series of attacks, including targeting a fellow prisoner with a glass jug.

In 1994, he took a prison librarian hostage, and three years later he did the same to three inmates at Belmarsh Prison in London.

With the Parole Board hearing approaching, Bronson said in the documentary he could 'taste freedom'.

"The system have labelled me for so many years untameable, untreatable, unpredictable, dangerous, blah, blah, blah. I've had every label you can think of," he said.

"But at the end of the day, what people don't realise, since George, my son, has come into my life, I've changed and... George has got me the best legal team in the world... I'm coming home, I'm definitely coming home."

Bronson's hearing is due to take place at the Royal Courts of Justice in London on 6 and 8 March.
