St. Tammany Parish Sheriff’s Office detectives are looking for a man who tried to rob a woman Wednesday night as she was making a deposit at a drive-up ATM outside a bank on La. 21 near Covington.

The man, who had a handgun, approached the woman’s vehicle from the rear, positioning himself between the vehicle and the ATM, according to the Sheriff’s Office. He grabbed the victim’s arm through her open window and demanded cash. She sped forward in her vehicle and got away unharmed, then called 911.

The robber was described as a black man, 20 to 25 years old with shoulder-length dreadlocks that appeared to have been dyed a light color. He had a black knit cap pulled over his face.

Anyone with information is asked to call Detective Matthew Vasquez at (985) 726-7830.
