Acting Detective Senior Sergeant Mick Fogell, who suffered minor injuries in the crash, said Sgt Glynn sounded in good spirits when he spoke to him on Monday.
The other officer, Detective Senior Constable Mel Staples, is on temporary leave for treatment for shoulder, finger and facial injuries.
The injured officers and three colleagues were walking east on the footpath to their Stirling Highway offices when the purple Ford Falcon, turning right into Church Lane, allegedly hit an east-bound silver Mazda, before hitting the three detectives.
The public and the uninjured officers provided medical assistance. The Mazda’s driver and the male and female occupants of the Ford were uninjured.
Detective Senior Constable Justin Cominelli said it appeared the detectives were not deliberately struck.
The Ford’s 39-year-old driver, from Parmelia, was charged with dangerous driving occasioning bodily harm, dangerous driving occasioning grievous bodily harm and having a blood alcohol level greater than 0.08.
He will appear at Perth Magistrates Court on October 24 and will be summonsed for drug items allegedly found in the Ford. Witnesses should call 1800 333 000.
