Six women who accuse Russell Brand of sexually assaulting and raping them in separate instances have described during a London trial their encounters with the British actor and comedian.

The women, who don't know each other, allege they were assaulted by Brand between 1999 and 2009 in locations including workplaces, a hotel room and a bathroom at a bar.

Brand, 51, has pleaded not guilty to three counts of rape, three counts of sexual assault and one count of indecent assault.
