Authorities Still Looking For Man Involved In Bomb Threat

Investigators are gathering more evidence to get an arrest warrant for the person calling in bomb threats at a Tyler elementary school. The latest threat was yesterday morning at Griffin Elementary.

Police and fire investigators were on hand to do a thorough sweep of the school. Bomb-sniffing dogs hunted for explosives but nothing was found. Authorities say they think all three threats came from the same man, and they're looking for whoever's responsible.

Captain Jeff Akin with the Tyler Fire Department said, "We're very anxious. We take that threat very seriously, even though a lot of times, threats are just threats, and there's really nothing to it. Nowadays, especially, bomb threats are not a joking matter."

As for the school's security, the district says they've asked all their teachers to be on high alert. A district police officer is also stationed on the campus.
