SA man hit three cars in less than an hour

A man will face court after hitting three cars in less than an hour while erratically driving a stolen vehicle through Adelaide.

Police say the stolen commodore was spotted in Magill around noon on Tuesday and soon after hit a police car. The driver then hit a second police car and another car before stopping in Glenelg around 12.30pm.

The driver, a 26-year-old Magill man, ran from the car and allegedly threatened two women with a knife before being tasered and arrested by police.
