NEW YORK (CNN) -- New York police were investigating a reported explosion in Times Square early Thursday, police said.

Two witnesses, a man and a woman, each told a local TV station they heard a "huge bang" from their hotel rooms, but there were no police or fire reports of serious damage or injuries.

"I was on the 44th floor and I heard it. I can feel it from up there," a woman told WABC-TV.

Police and fire squads cordoned off part of an area around Times Square. They gathered outside a military recruiting station with a large hole in the front window, The Associated Press reported.

Police could not confirm whether an explosive device went off in the area, the AP reported.

Subway service has been stopped to Times Square.
