(CNN) -- Surveillance video shows a man leaving a Hyattsville, Maryland, parking garage where an explosive device went off Tuesday, Prince George's County Public Safety Director Vernon Herron said.
Herron said authorities have identified the man in the video and are attempting to contacting him. He added that the man is a "person of interest" in the incident.
Prince George's County Fire Department responded to a call of an auto fire just after noon ET, Maj. Tyrone Forby said. Firefighters didn't see any flames, but noticed a suspicious package and they backed off, he said.
Herron said the county sent a robot in, and the robot confirmed there had been an explosion. The robotic device remained in the garage and bomb technicians headed in. Two agents from the Baltimore FBI field office were on the scene as well.
Authorities are taking the situation seriously, but Herron said they don't believe the incident is related to terrorism.
No other devices were found in the immediate area, Herron said. The damaged vehicle will be towed and inspected by agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives, he said.
Herron said officials are trying to contact the owner of the car. It was not immediately clear if the man seen in the video and the owner of the car is the same person.
