PORTLAND — Detectives have made a second arrest in connection with the Feb. 10 shooting death of Serge Mulongo in the Parkside neighborhood.

Moses Okot, 21, was arrested at 4 p.m. Thursday at Portland Police headquarters, after an interview with detectives. Okot has been charged with murder, and is scheduled to make his first court appearance this afternoon. He is being held without bail at the Cumberland County Jail.

According to a police affidavit, Okot was driving a vehicle belonging to 24-year-old Daudoit Butsitsi on the night Mulongo was shot.
