`A thief in Perth is stealing expensive motorbikes while on test rides after leaving dogs behind as security.
Police believe one man is responsible for stealing two bikes and abandoning two dogs in two separate thefts this month.
The first theft occurred almost two weeks ago after a Wanneroo man advertised his motorcycle for $10,000, officers say.
“A man arrived at his house with a dog and was given permission to take the bike for a test ride, leaving his dog with the seller,” police said.
“The man did not return with the bike, or for his pit-bull terrier dog.”‘
