Law enforcement was called to a key Hennepin County public works facility Tuesday after a reported bomb threat, which turned out not to be credible, authorities said.

The scene was just to the southwest of Hwy. 55 and Arrowhead Drive in Hamel, according to sheriff's spokesman Edgar Linares.

Medina Police Chief Ed Belland, whose agency responded along with the Sheriff's Office, said the threat no longer exists and no evacuation was necessary.

However, he added that a suspect in connection with the threat was being sought.

Emergency dispatch audio indicated that the "suspect is possibly heavily armed with hunting rifles and guns, is known to carry them."

County spokeswoman Carolyn Marinan had no information to disclose on whether someone with one or more guns was at large and being sought by law enforcement. Marinan did say the bomb threat was "determined the threat was not credible."

The facility in Medina houses the county's transportation departments and Hennepin County Emergency Management. About 250 employees regularly report there to collaborate on construction projects, traffic management, traffic safety, planning and maintenance activities, as well as to lead countywide emergency management efforts.
