The Sacramento Police Department is trying to identify a suspect in an attempted carjacking.

Last Thursday, a woman was walking to her car near the Arden Fair parking lot. The suspect walked up behind her, pointed a gun at her back and demanded her keys. The woman screamed, scaring off the suspect.

He's described as white male in his 20's with a thin build and short dark hair.

Anyone with information is asked to call Crime Alert at 443-HELP.
