WA Police are hunting a man and a woman accused of stealing items from Perth residents and businesses only to demand money for their safe return.

Kensington Detectives said there had been two incidents where money was requested for the return of stolen items, both on the same day earlier this year.

The owner's pet Chihuahua was inside the vehicle, and a short time later the offenders contacted the victim and demanded a sum of money for the safe return of the animal.
