Two teenagers are due in court today charged with the murder of vulnerable Dean Mayley in Ruislip Road, Greenford.

Ryan Beresford, 18, and a 17-year-old boy, who cannot be named for legal reasons, are accused of stabbing 24-year-old Dean, from Northolt, who had a mental age of nine, to death.

They will appear at Brent Magistrates' Court today, police said.

Two other 17-year-old boys have also been accused of the murder, as well as conspiracy to rob and possession of an offensive weapon. They appeared in youth court on Monday and were remanded in custody.
