A murder inquiry has been launched after the death of a man whose body was found in a common close in Glasgow.
Police at the scene have been interviewing locals
Thomas Longstaff, 34, of Dalmarnock Road in Bridgeton, Glasgow, was found dead in a tenement lobby in nearby Landressy Street on Monday.
Following a post-mortem examination, Strathclyde Police said they were now treating his death as murder.
Mr Longstaff was convicted of slashing a Celtic fan's throat in a sectarian attack almost 10 years ago.
He was jailed for 10 years in 1998 for the assault on a 19-year-old Celtic supporter at Bridgeton Cross.
The victim required 20 stitches and the cut narrowly missed his carotid artery and jugular vein.
Details of Mr Longstaff's injuries have not been revealed and detectives said inquiries were at an early stage.
A spokesman for the force said CCTV footage in the area was being studied.
He also asked for anyone in Landressy Street between 1500 BST and the time of his discovery at 1945 BST to contact Strathclyde Police.
