Children’s TV presenter Mark Speight has said he is ‘absolutely distraught’ at the death of his fiancee, Natasha Collins.

Mark, who has been bailed by police on suspicion of murder and supplying class A drugs, said he is assisting them with their inquiries and had nothing to do with Natasha’s death.

She was found in the bathroom on Thursday at the home they shared in north west London.

The BBC presenter discovered the body, a spokeswoman for Mark said.

Police said a suspected drug overdose was one line of inquiry they were considering.

Mark’s spokeswoman said: “Mark has been questioned by the police on account of the fact that the body of his fiancee, Natasha Collins, was found in the flat they shared.

“At the moment no one knows what happened. Mark found her body in the bathroom and immediately called an ambulance and the police. Mark was the only other person present in the flat and has therefore been questioned by police as a matter of course.”

A Scotland Yard spokesman said: “Police were called at 13.20 on January 3 to reports of a sudden death of a woman at a residential address in St John’s Wood.

“The woman, aged 31, was pronounced dead at the scene. A man in his 40s was arrested at the scene. He has been bailed to return to a central London police station on a date in early February.”

The death is being treated as ‘unexplained’, he added.
