If you're a fan of BBC quiz how Eggheads, you may want to sit down before reading on.

A former panellist for the hugely popular programme, which debuted in 2003, has been arrested on suspicion of murder.

According to numerous reports, CJ de Mooi, whose real name is Joseph Connagh, was detained by police at Heathrow airport yesterday after a European Arrest Warrant was issued in the Netherlands.

It has been established that Holland is seeking his extradition in relation to the murder of a mugger in the 1980s.

Mr. Connagh referred to an incident in his autobiography, CJ: The Autobiography of CJ De Mooi: My Journey From the Streets to the Screens, which ultimately raised suspicion among authorities.

Recalling what he described as a moment of self-defence against a mugger, Mr. Connagh wrote: "He caught me on the wrong day and I just snapped."

"I punched him so hard in the face, knocked the knife out of his hand and threw him in the canal. I fully suspect I killed him."

Mr Connagh is scheduled to appear at Westminster Magistrates' Court on Thursday.
