WASHINGTON — Metro Transit police are looking for six people in connection with an assault that happened on the Red Line last month.

The assault happened at about 5:30 p.m. Dec. 21 near the NoMa-Gallaudet Metro station, Metro says.

A group of teens became rowdy, a witness reported, and tried to rob a man, who was then attacked and left with a concussion and a broken jaw.

Metro says that there are no warrants for the six people of interest.

If you know these people, or know anything about where to find them, Metro asks you to call the Metro police at 202-962-2121, or to text your tip to 696873 (MyMTPD).
