Comedian Russell Brand has been accused of rape, sexual assaults and emotionally abusing four women during the height of his fame.

The alleged assaults occurred between 2006 and 2013, while he was a presenter for BBC Radio 2 and Channel 4, and include an assault on a 16-year-old girl.

He vehemently denied the “very serious criminal allegations” ahead of a Sunday Times article and an expected expose to be aired by Channel 4’s Dispatches programme tonight.

The allegations include crew members on his Big Brother spin-off being made to feel they were working as a “pimp” by approaching young women on his behalf, and that he raped a woman at his Los Angeles home.
