Police hunting for a man in connection with a murder after a woman's torso was found in a suitcase have warned he may have fled to Ireland.
Factory worker Vitautas Jokubauskas, from Lithuania, had been renting the property where the body was discovered with no arms, legs or head, said Cambridgeshire police.
Detectives said the 57-year-old has not been since May 30 when he was taken to work in Huntingdon by a friend.
Police have released a picture of Mr Jokubauskas, and are looking into the possibility that he may have fled to eastern Europe or Ireland, where he is known to have connections.
No formal identification has taken place on the remains found in Mr Jokubauskas' apartment, but police said they were keen to locate his partner, a Lithuanian woman described as being in her 40s, slim and with black hair.
Detectives found the body in Mayor's Walk, Peterborough, after reports from neighbours about a "nasty" smell coming from a room.
The torso was discovered when police attended the address at 12.30pm on Friday.
A cordon has been put up while officers conduct detailed forensic investigations.
The body has been removed from the house and a post-mortem examination is due to take place at Peterborough City Hospital on Monday.
Detective Chief Inspector Adam Gallop said: "We are very keen to trace Mr Jokubauskas and we are clearly very concerned for the welfare of his partner, who has also not been seen for some time.
"Investigations are ongoing to determine where this murder took place and our priorities are to locate Mr Jokubauskas and identify the body.
"I would urge anyone who thinks they have seen Mr Jokubauskas or recognises the description of his partner to contact police as soon as possible.
"Anyone who sees him should not approach him and should contact police immediately," added the senior officer, from the Bedfordshire, Cambridgeshire, and Hertfordshire Major Crime Unit.
He added that the murder was being treated as an isolated incident.
