Update at 2:45 p.m. — The package has been determined to be safe and the scene is being cleared.

Police, firefighters and the Arlington County bomb squad are staging at the corner of N. Courthouse Road and 13th Street in response to a suspicious package.

According to Arlington County Police spokesman Dustin Sternbeck, a maid in the Arlington Court Suites hotel on Courthouse Road found a small canister labeled “explosives.” It was brought to the hotel parking lot, where the bomb squad is examining it now.

“They’re taking all precautions as necessary,” Sternbeck said. “Until the canister has been deemed a non-threat, the area will remain closed.”

Authorities believe the canister might have been used in a training exercise by the Dept. of Defense, which rented out the hotel over the weekend. Courthouse Road is currently shut down between 13th Street and Route 50.
