Rochester, MN (KROC AM News) - A Pine Island man was arrested Friday by Rochester police for posting threats against Mayo Clinic and some of its employees on Facebook.

Police say the threats included a photograph of Adam Bussman holding what appeared to be a replica AK-47 gun. One of the posts said, "intern hunting I go."

Mayo security became aware of the threats and contacted police. The 36-year-old was taken into custody at his place of employment. Officers also found some methamphetamine in his possession.

Bussman was expected to be charged Monday.
