D.C. fire and police and inspectors with the U.S. Postal Inspection Service are responding to an incident involving a suspicious package at a U.S. Postal Service facility at 3300 V St. NE.

There are no immediate details on the incident or whether anyone was injured or how many people were in the facility at the time. The facility has been evacuated, according to a inspection service spokesman.

“We are working aggressively to determine whether the situation is related or involved to anything else that we’ve been working on in the last two days, said Postal Inspection Service spokesman Mike Romano.

The location screens and handles mail and packages sent to federal government agencies. It was set up in the wake of the Sept. 11, 2001, terrorist attacks and the 2001 anthrax scare.

On Thursday, separate packages containing incendiary devices and addressed to Maryland Gov. Martin O'Malley and his secretary of transportation flashed, smoked and produced an odor when they were opened, causing minor injuries to two employees and putting officials around the Washington region on alert.
