Deceased Man Peter Davis found at Perth Motel

West Australian Police have arrested a man following the discovery of a body in the car park of the Great Eastern Motor Lodge on Monday night.

The body is believed to be that of Peter Davis. Mr Davis was the managing director of Topseal Concrete Services in Forrestfield

Police have charged a 47-year-old Murdoch man, an employee of Topseal Concrete Services, with grievous bodily harm overnight in relation to the death. He will appear before the Perth Magistrate's Court this morning and it is likely that the charges will be upgraded to homicide.

Late Monday night there was an altercation in the rear car park of the Rivervale motel that involved two vehicles, one a Toyota Hilux ute (driven by the suspect) the other a Triton (drven by the son of the deceased), crash into each other.

Witnesses then saw the Hilux speeding away from the motel along Great Eastern Highway.

After the incident, the driver of the Triton involved in the crash called police and led them to a Mitsubishi Pajero also parked at the motel. When officers arrived at the scene they found a body in the rear of the four-wheel-drive.

A resident at the motel, Jared Liddicoat, told WA Today he heard a loud bang that got him out of his unit and onto the balcony, where he saw one car chasing another.

"There are skid marks down there and this Hilux had lined up this Triton up from a good 50 metres and just (sideswiped) him and reversed up and sped off," he said.

It is believe that the son of the victim Peter Davis, had been looking for his father, who had been missing since earlier on Monday. During that search he came across the occupant of the Hilux and followed him, ulimately being led to the body of his father.
