A murder victim's body has been found on the Marble Arch traffic island, one of London's busiest junctions.

The man suffered head injuries and was dead when paramedics arrived at 3am this morning.

By late afternoon his body was still on the island at the top end of Oxford Street as forensic scientists looked for clues.

Police cordoned off the island itself and pedestrian subways to the giant stone archway on it. Traffic on the road and at the nearby Tube station was unaffected.

A man in his 40s was arrested in connection with the murder.

Officers were tracing the victim's loved ones. He is yet to be formally identified.

Anyone with information can call 020 7321 7228 or Crimestoppers on 0800 555 111.
