A man carrying a gun robbed two people Wednesday night in Oak Lawn, police said.

The robbery happened about 9:30 p.m. in the 9100 block of South 52nd Court, police said. No one was injured.

Oak Lawn police are investigating the possibility that the alleged gunman was involved in similar incidents in a neighboring community.

According to police, a man carrying a black handgun approached the two people from behind and demanded money.

The assailant is described as a “young-looking” man in his early 20s, about 5 feet, 8 inches tall with a thin build, Oak Lawn police said. He was last seen running southbound on 52nd Court and wearing a black hooded sweatshirt with dark pants.

Anyone with information is asked to contact Oak Lawn police at 708-422-8292.
