Newly released video footage shows Julian Assange, the co-founder of WikiLeaks, behaving erratically during his stay in the Ecuadorian embassy in London.

The clip obtained by the Mail Online depicts Mr Assange punching and kicking the air and swinging his arms around, seemingly in an attempt to entertain himself.

Mr Assange’s movement was limited to a single bedroom that was previously an office and a small, austere kitchen. He was primarily alone, apart from his cat and a few permitted visitors, which included right-wing journalist and anti-war activist Cassandra Fairbanks.

Ms Fairbanks spoke to The Independent on Mr Assange's tenure in the embassy. "Julian was confined in a small living area inside a building for seven years with very little exercise, which has impacted his health. The Ecuadorian government is facing severe backlash for what they did and they are now desperately reaching to make him appear 'weird' or unsympathetic."

She continued, "The surveillance there was Orwellian and he was treated more like a prisoner than a political refugee with asylum since new Ecuadorian President Lenin Moreno took over. He was openly hostile towards Julian and made the conditions even worse than they needed to be."

"The poor guy couldn't go outside and they filmed him from every angle 24-7... and this is the worst they have?"

This video has come to light after reports that a team of doctors who evaluated Assange told the United Nations that his confinement in the Ecuadorian embassy was damaging to the point of being considered torture.

Dr Sondra Crosby has said the “cumulative severity of the pain and suffering inflicted on Assange—both physical and psychological—is in violation of the 1984 Convention Against Torture.”

Assange, who had resided in the embassy for seven years was recently ousted for allegedly violating terms of asylum.

It’s been reported that these violations include how Assange had smeared faeces on the walls of the embassy and leaked unsavoury images of the Ecuadorian president Lenin Moreno.

Both claims were categorically denied by Assange and his legal representation

Assange was granted diplomatic asylum from Ecuador in response sex-based offences in Sweden.

Assange believed answering to Swedish charges would lead to extradition to the US, where he was to be charged with a series of high-profile leaks that threatened American national security.

It appears as if these concerns were correct, as he was arrested by British police forces with a US extradition warrant and for breaching bail, for which he could serve up to six months in a British prison.
