PITTSBURGH — A founding member of a Scottish terror group was indicted on charges he e-mailed 17 bomb threats to the University of Pittsburgh earlier this year, disrupting campus life and forcing the evacuation of more than 100 buildings.

Adam Stuart Busby, 64, of Dublin, Ireland, was charged Wednesday with the e-mailed threats sent to the school between April 6 and 21, and also with e-mailed bomb threats against federal courthouses in Pittsburgh, Erie and Johnstown in June. He’s also charged with threatening Pittsburgh-based U.S. Attorney David Hickton — who led the investigation that resulted in Busby’s indictment — in a June 20 e-mail.

Busby is in custody in Ireland.

He has no known ties to Pittsburgh or Pitt, and Hickton wouldn’t comment on whether the threats are related to Busby’s activities with the Scottish National Liberation Army, a militant group that seeks Scottish independence.

Prosecutors also announced new charges against two Ohio men for some YouTube threats that claimed university computers had been hacked.

Alexander Wakeland, 24, of Loveland, Ohio, was charged Wednesday along with Brett Hudson, 26, of Hillsboro, Ohio, with conspiracy to target Pitt with Internet threats for the video and related e-mails and tweets.
