About two hours later (6:45am), a man entered a service station on Wanneroo Road, Balcatta and approached the counter armed with a cattle prod and demanded cash. The staff member complied and the offender ran from the store.

A short time later a dog squad unit was on patrol in Balcatta when a vehicle matching the description of the vehicle used in at least two of the offences was seen parked outside a setof units that were under construction. A search of the units resulted in the person of interest being located hiding in the roof space of one of the units. The man arrested and handed overto the Regional Investigations Unit.
