The BBC has launched an investigation into one of its radio presenters after he was accused of sexually assaulting eight female colleagues.

The unnamed presenter allegedly groped a multitude of women he worked with, according to the Mail Online.

The presenter, who cannot be named for legal reasons, would approach female staff from behind and put his hands up their skirts, according to claims.

He is reportedly being investigated by the BBC’s corporate security and investigations team.

The allegations cover a span of eight years, with the alleged assaults occurring at informal BBC events.

Only four of the eight women in question have made a formal complaint as the others were concerned about the potential damage to their careers, a source told the Mail Online.

Earlier this week, the BBC sent an email encouraging anyone to come forward with complaints in the wake of the Harvey Weinstein scandal.
