POLICE are questioning a man of 18 over the murder of nurse Cheryl Moss.
The man's arrest came yesterday, after a blue sports bag was found near St George's Hospital in Hornchurch, Essex, where the 33-year-old was stabbed to death on Thursday.
Police said the contents of the bag had led to the arrest, but refused to reveal what was inside.
The arrested man is not thought to be related to Mrs Moss, but it is not yet known whether he knew her.
He is being questioned at a police station in north London.
