Three people were robbed at gunpoint early Saturday morning in the South Loop, Chicago police said.

A man and two women were getting into a car when a black SUV bumped into the back of their vehicle just before 1 a.m., according to authorities.

When they got out of the car, four men got out of the SUV and aimed guns at them, demanding that they get on the ground. The victims’ wallets, cell phones, and keys were stolen, and the four men then fled the scene in the SUV.

According to police, no one was injured during the robbery, and no one is in custody. Area Central detectives are investigating the incident.
