Hunt steps up in BBC killing

Detectives investigating the murder of a BBC librarian are today returning to the scene where he died to try to track down witnesses.

Tom Brown, 27, was stabbed to death 200 yards from his front door in Southgate after a night out with friends.

Today officers will flood the area with appeal posters and carry out further door- to- door enquiries as they intensify the hunt for his killer.

Police do not yet have a description of the suspect but have ruled out robbery as a motive because Mr Brown's cash, bank cards, bus pass and mobile phone were still with him.

Detective Chief Inspector Keith Garnish said: "This appears to be a completely unprovoked attack."

Anyone with information should call police on 020 8345 3715 or Crimestoppers on 0800 555 111.
