Halifax Regional Police are investigating after an injured man was found lying on a sidewalk in Spryfield, N.S.

Police responded to the 400 block of Herring Cove Road before 6:30 a.m. Friday. When officers arrived, they found an unconscious man at the scene.

Police say the 51-year-old Halifax man was taken to hospital with life-threatening head injuries.

Several police officers, investigators, and a forensic identification unit are on scene outside the Hand in Hand thrift store.

“At this point we don't know what happened so we don't know exactly what we're dealing with, which is why we're hoping that anybody with information about the incident can come forward and help us,” said Const. Dianne Penfound, spokesperson for Halifax Regional Police.

Police seem to be focusing their attention on the parking lot, which has been blocked off with tape.The thrift store said on its Facebook page that it would be closed for the day.

A number of tarps and evidence markers have been placed at the site.

People who live in the area tell CTV News it's not uncommon to see police presence or yellow tape in the neighbourhood.

“Around this area it's not too too bad, but down at the other end it can get really bad,” says local resident Barb Jackson. ‘The police are always down at the 500 block and stuff. Night time I get scared when I'm walking.”

A dark-coloured Hyundai Santa Fe was also towed from the parking lot of the thrift store. Police later confirmed the vehicle belongs to the man found on the sidewalk.

Anyone with information is asked to contact police.
