A woman was robbed of her money Wednesday night outside a Lawrence gas station, police say.

Around 9:20 p.m., officers were dispatched to the 1000 block of N. Third St. regarding a possible robbery, said Lawrence Police Sgt. Amy Rhoads. There, officers found a woman who said she had just been attacked by three other women.

The woman told police she was inside a gas station when a woman approached her and asked for money, Rhoads said. When she declined, the woman left the store and headed toward a white sedan.

Leaving the gas station, the reported victim began walking north on Third Street when three women attacked her from behind and demanded money, Rhoads said. All three suspects left the scene before police arrived.

The woman suffered minor injuries and was treated on the scene, Rhoads said.

Police are investigating the incident, Rhoads said.
