BATON ROUGE- Authorities arrested a man after he made threatening phone calls and videos where he claimed to have explosive devices.

Authorities say Dean Hebert, 35, called a man and left a voicemail saying it was 'a great day to die.' Hebert also visited the victim's workplace and left his business card.

The victim's staff used the information on the card to look Hebert up on social media. His online profile included a video in which he appears to have an explosive device. BRPD's Explosive Ordinance Disposal division later identified the object as a fake explosive device.

Neighbors and witnesses confirmed that Hebert had also set off a series of small explosions around the building.

When police responded to Hebert's house, they also found drug paraphanalia and a jar of what appeared to be marijuana.

Hebert was arrested on a list of charges, including possession of a fake explosive device.
