Boston police officials said Thursday they have begun increasing security presence at major media outlets in the Boston area after a shooting at a newspaper in Annapolis, Md., left at least five people dead and several wounded.

“While there are no credible concerns or information detailing similar threats directed towards media outlets in Boston, Commissioner Evans has called for increased and directed patrols in and around various media agencies throughout the city,” Officer James Kenneally, a department spokesman, said in an e-mail.

Officers will “make a point” to increase their presence at media outlets by stopping and driving by more frequently, Kenneally said.
