Arson investigation after video shows fire destroying converted ambulance used by DC non-profit

WASHINGTON - Arson investigators are searching for a man they say set fire to a converted ambulance used by a D.C. non-profit group.

Surveillance video captured the incident early Saturday morning in an alley in between Parker Street and K Street in northwest D.C.

In the video, a man can be seen walking to the ambulance at the end of the alley, putting something down, and then walking away. About 15 minutes later, the ambulance erupted into flames.

Fire investigators do not believe the incident is connected to any other case.

The ambulance was converted and used by the non-profit group BeatBox DC, and the group's founder, Peter Luce, said they used the ambulance to bring music and arts to the public.

Fire investigators told FOX 5 they are still investigating what ignited this - they also believe it is likely that somebody crossed paths with the suspect, either before or after the incident.

D.C. Fire and EMS ask that if you have any information to please call 202-673-3370.
