Amnesty International urges women to come forward with Russell Brand concerns

Comedian performed at charity's gigs during period in which he allegedly committed rape and sexual assault

Amnesty International has urged women to come forward if they have any concerns about the behaviour of Russell Brand during his participation in two of the charity's standup comedy events in 2006 and 2012, after the publication of allegations of rape, sexual assault and emotional abuse.

It follows the announcement by a charity which supports vulnerable women recovering from addiction that it would sever links with Brand. The Trevi women and children's charity said it had ended its association with Brand and his charitable fund, the Stay Free Foundation.
