The son of a head teacher who stormed the Churchill cafe in North London has been accused of kicking a professor who has cancer and punching a woman lecturer during protests over lecturers' pensions.

The School of Oriental and African Studies (SOAS) university has launched an investigation into student Hamish Anderson, who is alleged to have taken part in violent protests in support of lecturers last Friday.

Anderson hit the headlines in January after storming the Blighty cafe and denounced Britain's war-time leader as a war criminal and a racist while chanting Marxist slogans.

The hard-left activist's mother received an OBE for services to education. Despite his comfortable upbringing, he is accused of leading a 'hard picket' with fellow Blighty cafe protesters Halimo Hussain and Nisha Phillips and blocked the entrance to the SOAS building last week.

The music and history student is accused of kicking Professor Lawrence Saez, 52, who had just found out two days earlier that his latest bout of chemotherapy had been unsuccessful.

Professor Saez, who broke the picket to work, told The Times: 'Over the last two years I have been a cancer patient... frankly, I'm not sure how long I have left. I try to enjoy life to the fullest and I get a great deal of enjoyment from my work.

'To have these punks prevent me from teaching is very upsetting.'

Anderson is also alleged to have punched and kicked Dr Idil Osman, 34, as she tried to pass the picket line. Dr Osman claimed the group's actions 'reeked of privilege'.

She told The Times: 'Hamish was the violent one. He kicked me and punched me on the upper body. The others watched him assault me and then told me off for "shouting at them".'

She continued: 'I'm a black Muslim woman who had to work hard to become a lecturer. I've got other struggles and a PhD loan to pay off. I can't afford to pay into a pension.'

The welfare and campaigns officer at the University's students union said the claims made by the two lecturers were not supported by CCTV footage.

A spokeswoman confirmed the university had received 'a number of complaints' and was investigating.
