NEW YORK, May 16 (UPI) -- Police in New York said they were investigating an incident in which a bullet hit a wall in Yankee Stadium.

The slug came within feet of a night custodian who heard it strike early Sunday, the New York Post reported. The shooting occurred about 7 hours after the end of Saturday's game between the Yankees and Mariners and 12 hours before a Sunday afternoon game.

Investigators were unsure whether the shot was fired from inside the stadium or from a rooftop some distance away.
