Officers were called to Old Post Office Court, near the Walnut Tree Shades pub, shortly after 5pm today to assist the ambulance service.

Police have cordoned off an alleyway opposite the pub where it is believed the body was found.

A member of the public, who did not want to be named, said a man turning his car around in the alley spotted the body.

He said a pub customer then went over to check the man's pulse.
