Metropolitan and University Police Department officers cleared a “suspicious vehicle” containing gas cans, aluminum tubing and rubber tubing near the GW Law School at about 8 p.m. Sunday.

The objects in the Oldsmobile parked on 20th Street between G and H streets were partially concealed by papers, UPD Chief Kevin Hay said. UPD officers who observed the piping found it suspicious and called MPD.

Officers closed the block off until MPD’s explosive-sniffing dogs verified the area was safe. After interviewing the driver and determining there was no danger, officers cleared and left the scene.

MPD public information officer Paul Metcalf said the department received the initial call at 7:20 p.m. An officer who declined to provide his name said the tubing in the car was part of an air conditioning unit.

D.C. Fire and EMS also responded to the scene.
