HARTFORD, Conn. (AP) A Wethersfield man has been arrested on federal charges of calling in hoax threats to emergency services to draw responders, such as SWAT units and bomb squads.

Federal officials say Matthew Tollis was arrested Wednesday on charges of making calls earlier this year in Connecticut and other states.

The offense is called ``swatting,'' referring to false calls to draw SWAT teams.

The 21-year-old Tollis and others are accused of using Skype to make hoax threats involving bombs, hostage taking, firearms, and mass murder.

He was identified as a participant in at least six incidents, including a bomb threat in April to the University of Connecticut and to schools and other locations in New Jersey, Florida, Texas and Massachusetts.

Tollis is detained. His Hartford lawyer did not immediately return a call Thursday seeking comment.
