A second Hollywood actress has been identified as an alleged member of a sinister sex cult. 

Battlestar Galactica star Nicki Clyne is said to belong to the DOS cult - a sinister organisation that brands its members with the initials of their leader, Keith Raniere.

DOS is said to be a secret society for the highest ranking female members within the self-help group NXIVM.

Clyne's alleged membership of the organisation was reported by Sun Online, which also claimed to have seen a stash of pornographic images that are used to blackmail followers tempted to leave. 

Clyne is believed to have been one of those who handed over pornographic material in a bid to prove her loyalty.
