Woman threatened with knife in SA break-in

A woman has been threatened with a knife and a car stolen during a break-in near Port Adelaide.

Four men broke into an Ottway home just before 5:30am on Friday and confronted the three occupants, pushing one man to the ground and threatening a woman with a knife before punching her.

The group then stole a mobile phone, cash and a black 2010 Holden Cruze with registration plates S787AJO.

Police have released images of the men in the hope someone may be able to identify them.
