St. Peters, MO (KSDK) -- The St. Charles Prosecuting Attorney's Office charged a woman for robbing a BP gas station in St. Peters then leading officers on a chase, police say.
41-year-old Helen Denson is charged with first degree robbery, armed criminal action and resisting arrest.
Police say around 2:35 a.m. on August 14, Denson allegedly entered the BP Gas Station at 150 Salt Lick Road and displayed a rifle to the female clerk.
Denson allegedly demanded money and lottery tickets from the clerk and fled the area in a black 2000 Chrysler 300.
Police say Denson had her face covered with a gray scarf during the robbery, however the clerk was still able to provide a good physical description.
Shortly after the robbery call, a St. Peter's officer saw Denson driving eastbound on I-70 and observed that she met the robbery suspect description. The officer turned on his emergency lights in attempt to pull her over, but she refused to stop.
Police say Denson exceeded 100mph on the highway before exiting on Zumbehl Road and leading police on a chase through the streets of St. Charles.
Police were able to apprehend Denson when her vehicle struck a curb on North Second Street near Olive Street, causing her to lose control of the vehicle.
Police say there were no injuries during this incident.
Denson's bond is set at $100,000.
