A South Carolina man was arrested yesterday for allegedly threatening to set off an explosive device at Darlington Raceway. The track is where the NASCAR season is set to restart May 17, 2020.

Darlington County Sheriff’s Investigators said that Michael Donovan Avin of Darlington phoned in threatening messages to the track.

Full details of the message have not yet been revealed, but the arrest warrant stated that it “described a possible explosive device and the results it may create to further his cause.”

It also said that he called another location in Darlington and claimed to have access to 125 tons of bomb-making materials.

Avin was charged with possession, threatened or attempted use of a weapon of mass destruction for an act of terrorism, not resulting in death.

The NASCAR event will be held without spectators in attendance.
