A Subway store in Mandurah was ram-raided overnight but it appears nothing was stolen.
About 3.35am, a dark-coloured Nissan was driven through the front doors of the store on Old Coast Road in Falcon.
A passenger in the car then entered through the smashed glass doors and rummaged through the store.
He eventually exited the store and the car left the area.
It is believed the offenders left empty-handed.
Anyone with information is asked to call Crime Stoppers on 1800 333 000.
