An Indiana man is accused of making a bomb threat Saturday against the Gridlife Festival in South Haven, Michigan after he was kicked out of Gingerman Raceway.

The Van Buren County Sheriff’s Office says the 35-year-old man from Plymouth put a bag near the music stage and told detectives there was a bomb in the bag.

It did not contain any explosives, but a white powder in the bag tested positive for ketamine and he also had suspected LSD on him.

He was arrested on charges of a false report of a bomb threat, false report of a terrorist threat, resisting and obstructing police, possession of ketamine, and criminal trespass.
