Police said a number of items were loaded into a trailer attached to the utility.
“During the incident, the 38-year-old man linked to the Isuzu was detained by two men associated with the business premises,” a WA Police spokesman said.
“It will be alleged the two men used excessive force to detain him, causing him to receive serious injuries which required medical treatment in hospital.” The injured man has been released from hospital.
Police are looking into the circumstances surrounding his presence at the business premises and his link to the stolen vehicle.
A 49-year-old man and 29-year-old, both from Stake Hill, were jointly charged with one count of grievous bodily harm.
They will face Mandurah Magistrates Court on July 1.
