A jury has found Nigerian master’s student Somtochukwu Okwuoha guilty of making terrorist threats against Dundee University.
The Perth Sheriff Court heard that Mr Okwuoha, 26, told university staff he planned to carry out mass murder on the university campus between December 2021 and June 2022.
Witnesses described how Okwuoha claimed he had a military background and was capable of making bombs and unleashing a deadly virus on the city.
Keith Mackle, 58, now retired director of student services, told the court he became aware of “serious concerns” in the autumn of 2021.
He said staff members received emails making terrorist threats.
One said: “Expect a massive bomb explosion at the University of Dundee. I have contacted ISIS terrorists to plant bombs on campus.
“I can assure you staff and students will die in great numbers. 9/11 will be a joke compared to what will happen.
“Blood will spill and flesh will be scattered.”

Accommodation officer Shane Taylor told the court Okwuoha accused him of being racist and said he planned to wipe out Scottish people as revenge.
Okwuoha, who was studying international energy, was found guilty of seven charges.
He was found guilty of threatening to commit mass murder, using biological weapons, revealing staff details to international authorities, and claiming to have planted bombs.
He was also found guilty of threatening to behead police officers and detonate bombs he had planted at Dundee University.
Okwuoha will be sentenced next month and could face deportation to Nigeria.
