Police have descended on a suburb in Perth’s north following a suspicious death outside an apartment block.

At around 9.45am on Wednesday, police received a report from St John paramedics that the body of a woman had been found on Grand Boulevard in Joondalup.

Police say the woman was left at the scene by a yet to be identified male.

Residents and witnesses told PerthNow that around 30 officers were present outside the Arthouse apartments until around 12.30pm.

Resident Ken Forrest said he came across the scene at 8.30am.

“As soon as I walked out there was a bunch of tape around the area and an ambulance. (The police) couldn’t tell us what happened,” he said.

Fellow resident Mohammad La Faraj said the police presence was unusual for the area.

“I just hope that our neighbours are safe, I just hope nobody’s hurt. It’s good to know that there are people working on it,” he said.

Police had cordoned off a section of the road right outside café Cinnayum and seized CCTV footage from the apartment complex and neighbouring businesses.

Detectives are still investigating the circumstances surrounding the woman’s death, and urge anyone with information to contact crime stoppers.

A St John Ambulance spokesperson says paramedics are cooperating with police.
