A Baltimore County police captain was arrested at a St. Patrick's weekend sobriety checkpoint and has since been moved to administrative duty, the department said in a statement Monday.

Capt. Matthew McElwee, 43, of the Franklin Precinct in Reisterstown, received citations from the Carroll County Sheriff's Office accusing him of driving while intoxicated and driving while under the influence. He did not respond to requests for comment Monday.

Baltimore County police said he was driving his personal vehicle and was not carrying a weapon at the time.

McElwee has been transferred to the operations bureau pending the results of the case and an internal investigation, county police said. The assistant commander of Precinct 3, Lt. Stephen Doarnberger, will serve as acting captain.

According to the Carroll County Sheriff's office, McElwee, of Hanover, Pa. was arrested on suspicion of alcohol impairment and released to a sober driver on citations when he refused to submit to a blood alcohol concentration test.

The sheriff's office, along with Westminster Police, Maryland State Highway Administration and Catherine's Cause were conducting a sobriety checkpoint from 11 p.m. Saturday to 1 a.m. Sunday in the 2200 Block of Hanover Pike in Hampstead.

Of the 260 vehicles that passed through the checkpoint, police made two arrests, including McElwee along with a 24-year-old man, who received citations for possession of marijuana.

McElwee has been employed by the department since 1987.
