Brookfield police are investigating an armed robbery at an Ogden Avenue gas station late on July 22 in which a lone gunman demanded cash from three women who had stopped to gas up their vehicle.

No one was injured, but police reported that the victims – a 49-year-old woman and a 35-year-old woman, both of Oak Forest, and a 45-year-woman from Jersey City, New Jersey — were so shaken up by the robbery that they didn’t immediately call police, waiting some minutes before informing a gas station employee what had happened.

According to police, the victims drove into the BP station, 8856 Ogden Ave., around 9:30 p.m. and the driver gassed up the vehicle before entering the minimart.

While she was inside, the offender, described as a Black male, about 5-foot-8, between 25 and 35 years old, wearing a dark hoodie pulled up around his head, a black facemask, black jeans and gym shoes and white winter gloves approached the driver’s side door, leaned in the open window, pulled out a handgun and demanded cash from the two women still inside.

When the driver returned to the car, the offender also demanded cash from her, which she turned over. The offender then returned to a dark-colored sedan that was waiting on Forest Avenue just south of Ogden Avenue. The car was last seen heading east on Ogden Avenue.

During their investigation, police learned through surveillance camera video that the offending vehicle traveled south on Prairie Avenue from the 3600 block to Ogden Avenue, where it turned east and then south onto Forest Avenue before making a three-point turn and parked, facing north.

The offender exited the vehicle and crossed Ogden Avenue, heading toward the gas station at about 9:30 p.m. He is seen jogging back east on Ogden Avenue and then south through traffic toward the waiting vehicle two minutes later.

The victims told police that they had not stopped at an ATMs prior to gassing up the car and did not notice any vehicle following them at any time.
