Erratic SA teen driver hits cyclist

An unlicensed teenager has been arrested after allegedly driving erratically in northwest Adelaide, hitting a cyclist.

Police received multiple calls of a white Commodore colliding with several cars and a cyclist in Osborne and Taperoo on Thursday afternoon.

They say the cyclist fortunately only sustained superficial injuries and the 19-year-old man was arrested at a Taperoo property shortly afterwards.

He's been taken to Queen Elizabeth Hospital and police are appealing for any witnesses to contact them.

The man's expected to appear in court in Friday on multiple driving offences.
