LONDON (AP) — British police say they have arrested a man and a woman in relation to a probe into child abuse on Twitter.

Metropolitan Police say the pair, both in their 40s, have been released to return in November pending further questioning. They were arrested at a London apartment Friday.

Police took action after receiving information from the Sunday Mirror newspaper, which carried out a probe into sex offenders operating on the social media network.

The tabloid reported that it found 200 Twitter users who openly expressed interest in sexual images of children, and that it passed on its findings to the Metropolitan Police's unit tackling pedophiles.
