A man has been shot by police after allegedly trying to ram a stolen car past a police vehicle during a confrontation in the Perth suburb of Seville Grove this morning.

A police spokeswoman said police spotted a stolen Subaru Impreza hatchback parked in the driveway of a home on Firetail Court about 11:00am.

When the police car drove up behind the vehicle, which contained two occupants, the driver of the Subaru allegedly reversed into the police vehicle, causing it major damage.

The spokeswoman said the passenger from the Subaru fled and was pursued on foot by an officer.

The Subaru driver allegedly continued to ram the police car in a bid to manoeuvre past.

One of the officers then fired on the Subaru, leaving a man in his 30s with a gunshot wound to his shoulder.

Police administered first-aid and St John Ambulance paramedics were called to the scene, transporting the man to Royal Perth Hospital for treatment.

The man is in a stable condition with non-life threatening injuries.

Dozens of officers from the Homicide Squad and the Police Internal Affairs Unit are at the scene conducting inquiries into the shooting, and part of the street has been cordoned off with police tape.

Inspector Geoff Desanges said Internal Affairs would conduct drug and alcohol tests of the officers involved and also consider the mental wellbeing of all involved in the incident.

"A police officer has just discharged a weapon, which is a very confronting thing to have to do during the course of your duty, so we have to look after those officers," Inspector Desanges said.

'Why didn't they taser him?'

Relatives of the occupants of the home who gathered around the crime scene said police were being tight-lipped about what took place.

Deaths in Custody Watch Committee spokesman Mervyn Eades said the shooting of an Indigenous man by an officer just weeks after the WA Police Commissioner apologised for past mistreatment of Aboriginal people should cause concern.

"The last resort should be shooting anyone. They've got tasers, they used the taser on another boy, why didn't they taser him?" Mr Eades said.

"We're very alarmed and shocked, after the Police Commissioner's statement a few weeks ago where he came out and said sorry to us.

"We hope it's investigated properly and fully investigated, I've already contacted Deaths in Custody lawyers in Sydney and we'll be monitoring that."

Mr Eades said the wider Aboriginal community would be impacted by the incident.

"As a wider community we're disgusted that a young man has been shot while being arrested," he said.

"It's going to impact on the wider community, you know, especially our younger ones and that who already have so much fear from the police.

"It's just something that's been happening to our people for a very long time and we as a community, we're sick and tired of this sort of brutality happening within our community by the police force towards any of our men and women."

He said the man's mother visited two hospitals before she found where her son was being treated.

Union providing support to officer

WA Police Union President George Tilbury said they had dispatched a team to ensure the health and welfare of their members involved in the incident.

"Our members have been through a very difficult and dynamic situation," Mr Tilbury said.

"Thankfully, they have not been injured and are coping well."

He said because the incident was subject to investigation, no other details could be provided.

The property is directly adjacent the back of a school, which remained open today.
