A 19-year-old man has been charged after a car crashed into a house in Tuart Hill this morning.
Police were called to the Park Street property about 1.15am and found the house and car had been significantly damaged.
"It is estimated that approximately $80,000 damage has been done to the house," police said.
Police allege the 19-year-old man from Tuart Hill refused to provide a "sample of breath" at the crash scene.
"Once back at Mirrabooka Police Station he again refused to provide a sample of his breath," police allege.
The man has been charged with refusing a breath test.
In a separate incident, the Dog Squad was called in after a car crashed through a Thornlie house's fence into a parked car last night.
The crash happened on Spencer Road at 10.50pm.
"The first police unit on the scene was from the dog squad, and it was established that a number of people had run from the crash scene towards Roe Highway and into bushland," police said.
"Police dog Jose was deployed and located two persons of interest running across Roe Highway.
"Jose and his handler intercepted them in bushland and they surrendered after being challenged by the handler.
"A short time later a third person of interest was located by Jose and was also taken into custody without incident."
Police will continue to investigate the Thornlie crash.
