An Alabama man was arrested Thursday after he reportedly threatened to return to Walmart with a homemade bomb after he was denied a refund.

Christopher Lee Brown, 46, of Cullman was arrested on a warrant for making a terrorist threat. His bond was set at $2,500.

Hartselle police report that Brown went to Walmart to return several propane bottles.

When the store said they were unable to refund Brown for the bottles, Brown reportedly threatened employees and told them he would come back with a homemade bomb made from the propane bottles.

Police said employees were concerned about their safety and the safety of the customers after the threat was made.
