Police want to speak to four men after a woman was assaulted while sitting in her car at Mawson Lakes overnight .

The group were in a Ford sedan when they pulled up beside her at the traffic lights on Salisbury Highway just before 11pm.

One of the men grabbed her as he jumped into the back of her car, before she managed to accelerate, causing him to fall out .

He is described as about 18 years, with a skinny build with a shaved head.
 

Police are also hunting a man after an indecent assault at Elizabeth South last night.

The woman was walking in a reserve near Kittering Rd when she was attacked by a man on a bike at about 6pm.

He is described as between 30 and 40 years old, with a chubby build and big hands, wearing dark clothing.
