ST. LOUIS COUNTY • Internal affairs investigators in the St. Louis County Police Department are probing the actions of an officer after residents complained that he drove too quickly through their subdivision and arrested a man who took issue with him.

Authorities are conducting an administrative review of the officer's actions but said they had not received a formal complaint.

The incident happened over the weekend in the 1100 block of Pinrun Drive. Paramedics had arrived at a home for a sick case for a suspected drug overdose. They asked police to "expedite" arriving to the scene, said Police Officer Brian Schellman, a spokesman for the department.

The officer, whom Schellman refused to identify, drove into the subdivision east of Highway 141 in his patrol car. Two residents interviewed by the Post-Dispatch say the officer was driving with his lights but no siren on and coming too fast around the corner and down the street.

"He was flying down the road. We thought he was going to ram the firetruck," said Brent Williams, one resident. "He had to be doing 50 or 60 mph. Had to be."
