A man has been arrested after an armed robbery at a petrol station in Adelaide’s inner-south.

The man allegedly entered the BP On The Run on King William Rd in Unley about 12.40am on Tuesday and threatened staff with a gun.

He left the service station with cash.

No one at the station was physically injured.

Patrols searched the area and found a man hiding nearby.

An Unley man, 23, has been charged with aggravated robbery and will appear in the Adelaide Magistrates Court later today.
