A device that appeared to be a pipe bomb was identified Thursday outside the gates of Indianwood Golf and Country Club, site of next week's U.S. Senior Open, according to the Associated Press.
Oakland County Sheriff Michael Bouchard said in a statement there was no credible, specific threat to the club or the tournament. He considered it a "random act."
A bomb squad arrived at the Detroit-area club to investigate what was a homemade device.
The tournament begins July 12.
