Police allege that at around 6:15 am on Tuesday, February 23, a patrol sighted a black commodore sedan speeding north on Goodwood Road which then collided with a Toyota Corolla at the intersection between Goodwood and Dudley Road.

The 40-year-old male driver of the Corolla was taken to the Flinders Medical Centre with non-life-threatening injuries, while a 31-year-old female passenger in the commodore was taken to the Royal Adelaide Hospital.

The driver of the commodore fled the scene on foot after the crash, and escaped police detection despite an “extensive search”.

Police now believe 22-year-old Johnson could be using a stolen 2016 grey Isuzu DMax, registration plate WNZ-291.

Johnson is described as 175cm with a slim build and short brown hair with distinctive tattoos on his face, and police are urging members of the public not to approach him as he is considered dangerous.

SAPOL said anyone with information about Johnson’s whereabouts should contact the police assistance line on 131 444.
