LINCOLN, Neb. (AP) — A 26-year-old Lincoln police officer has been accused of buying alcohol for his teenage girlfriend.

The Lancaster County Sheriff’s Office says in a news release that Officer Scott Bierle was cited Tuesday with procuring alcohol for a minor. Bierle has been placed on modified duty and has a court date set for Feb. 13.

Sheriff Terry Wagner says the police department asked his office to investigate the allegations. He says investigators determined Bierle bought alcohol for his 19-year-old girlfriend at a bar on Dec. 16 at a gathering of off-duty officers. The teen was also ticketed on suspicion of being a minor in possession of alcohol.

Bierle has been with the Lincoln department since December 2015.
