A group of teens reportedly discharged a fire extinguisher on a Red Line train this morning near the Rhode Island Avenue station, according to a rider who tweeted a photo of the incident.

Metro spokesperson Dan Stessel confirmed that Metro Transit Police recorded the incident “as a fire extinguisher discharge only.” Although there were no reported delays, injuries, or impacts to service, Stessel said he could not confirm the time of the incident or a description of the alleged teens. In a separate tweet, the rider, @thinkerhoff, indicated that it occurred around 8:45 a.m. after the group boarded at Gallery Place; the train was going to Glenmont.
