Metro has temporarily discontinued service on part of a bus line in Southeast D.C. after a rider was shot Friday night while on board.

A man riding the W8 bus was shot about 10:30 p.m. Friday as the bus traveled in the 2400 block of Elvans Road SE, Metro said Monday night.

The shooter fired from outside the bus, hitting a man believed to have been an unintended target, a Metro spokeswoman said. The victim ran from the Garfield-Anacostia Loop Line bus and was found outside an apartment complex. He was rushed to a hospital with non-life-threatening injuries.

In response to the shooting and "several recent security incidents," Metro will cut service to Elvans Road after 7 p.m. for seven days. Riders will have to board instead on Stanton Road. The walk from the western-most part of Elvans Road to the closest bus stop on Stanton Road is about 0.3 miles.

No one has been arrested in connection to the shooting, Metro said. Metro Transit Police are reviewing surveillance footage.

In a separate incident nearby, a bus driver reportedly was threatened July 28 at 19th and Savannah streets SE, Metro said.

Amalgamated Transit Union Local 689, which represents bus drivers, is urging Metro to protect riders and drivers.

"We are impressing upon WMATA to do everything it can to insure the safety of the bus operators, including canceling service, if necessary," the union said in a statement. "With this incident, we are reminded of the need for an increased police presence on Metro buses."
