Metropolitan Police officers are investigating a Saturday morning drive-by shooting just blocks from the White House that fired bullets into a half-dozen local shops.

MPD officers responded to the sounds of gunfire at about 3 a.m. on Saturday, according to MPD public information officer Saray Elon. Bullets hit the front windows of six businesses near 17th Street and Pennsylvania Avenue, Elon said.

Posey Eitzen, an employee at Brewood Engravers on 17th Street and Pennsylvania Avenue, which has boarded up one side of its store, said she saw at least five businesses with holes shot in their windows.

At least one 9 mm bullet was found inside Brewood Engravers, The Daily Caller reported.

An employee at the neighboring Caribou Coffee also confirmed that its front windows were shot and are covered in plywood boards.

The coffeeshop is a popular spot for White House staffers to meet, and typically has a large Secret Service presence, according to The Daily Caller.
