State police at the Fern Ridge barracks said that a checkpoint they conducted from 9 p.m. Sept. 26 to 2 a.m. Sept. 27 at the intersection of Route 209 and Dairy Lane in Chestnuthill Township resulted in three arrests.

Police said two suspects were charged with driving under the influence of alcohol or a controlled substance and one person was charged with a misdemeanor drug arrest. That person was also arrested on a felony drug warrant.

The checkpoint was designed to deter drivers who are drinking, using drugs or abusing prescription drug medication from getting behind the wheel and placing themselves and others at risk, police said.
