A device that looked like it was designed to blow up but contained no explosives was left at an entrance to Montana TV station and destroyed by police, authorities said.

The device dropped off Monday evening by a man who said "this is for you" was wrapped in electrical tape and had wires and what looked like batteries and a timer, KTVQ-TV News Director Jon Stepanek said. The device and a plastic tote were left at the TV station on the same day that Cesar Sayoc of Florida appeared in federal court on charges alleging he mailed pipe bombs to Democratic politicians and critics of President Donald Trump.

The tote had "religious writings" on it, Gartner said. A bomb squad robot was used to examine the items and authorities blasted them with high pressure water.

No arrests have been made. The suspect was described as tall, slender and dark skinned wearing a black hoodie
