A murder probe has been launched after a homeless man was found dead in Northern Ireland, police said.
Piotr Krowka, aged in his late thirties, was discovered at a derelict former parochial house where he had been sleeping rough on the Glen Road in Maghera on Tuesday afternoon.
He had suffered serious injuries to his head and body.
The vulnerable man from the Polish community had been living in the area for a number of years, the PSNI said.
Detective chief inspector Geoff Boyce said: "He suffered serious injuries to his head and body and we are working to establish the circumstances of this incident and determine the precise sequence of events that culminated in the tragic death of this man."
Detectives launched a murder investigation after receiving the results of a post-mortem examination.
Mr Boyce added: "I am keen to identify Piotr's movements between Good Friday and Easter Tuesday when his body was discovered, and I would appeal to anyone who was in contact with or who may have witnessed Piotr during this time to please contact us.
"I am also keen to hear from anyone who may have noticed anything suspicious at this house during the time frame to contact detectives at our incident room at Magherafelt PSNI Station."
