RUC detectives are still questioning several men after the body of a man in his 40s was discovered in east Belfast on Wednesday morning. Mr Norman McKeown's death is being treated as murder after a post-mortem revealed that he died in suspicious circumstances.
Mr McKeown is believed to have been homeless. His body was found at the bottom of stairs at a house in Kingswood Street. Neighbours say he was not known to them.
The RUC has appealed to anybody who saw Mr McKeown in the Albertbridge Road, Templemore Avenue or Kingswood Street areas late on Tuesday to contact it.
