Police are appealing for information after the unexplained death of a 21-year-old man following a night out with friends

Police are appealing for information after a 21-year-old student was found dead with unexplained injuries following a night out with friends.

Harry Loker was found collapsed outside an address in Royal Park Avenue in the Hyde Park area of Leeds, at about 9.17am on Friday. The Leeds Beckett University student had a number of injuries and was pronounced dead at the scene, West Yorkshire police said.

A police spokesman said the injuries cannot presently be accounted for and the death is being treated as unexplained. He said Loker had been out socialising with friends in Leeds city centre on Thursday evening and is believed to have left to go home in the early hours of Friday.

DCI Jaz Khan, of West Yorkshire police, said detectives are trying to establish the student’s movements after he left the city centre. He appealed to anyone who may have seen him on Thursday night or Friday morning to come forward as they may have “vital information” that could help the inquiry.

Khan said: “We are appealing for information to help us to understand the circumstances leading to Harry’s death. At this time, there are a number of injuries that we are unable to account for and are keeping an open mind as to how these may have been sustained.”

He continued: “Harry’s family are understandably devastated with the news and officers are continuing to support them at this time.”

Loker’s family said they were “broken” by the death of the “devoted” and “perfect” young student. In a tribute, they said: “Harry was a devoted son, brother and perfect grandson and we could not have asked for more. We as a family were extremely proud of Harry and all his achievements and he will be sorely missed.

“This terrible, terrible incident has broken us as a family and leaves pain in our hearts.”

Anyone with any information, or who may have seen Loker, is asked to contact Leeds District CID on 101, quoting 1317426310, or Crimestoppers anonymously on 0800 555111.
