A man headbutted another man in a Dundee student union in an unprovoked attack.
Ivans Pluscs, 21, of Fyffe Street, was jailed for 18 months after admitting one charge at the sheriff court.
He admitted assaulting Stuart Milne by butting him on the head, causing him to fall to the ground and strike his head, all to his severe injury.
Pluscs carried out his attack on October 29 last year, at Dundee University Students Union, on Balfour Street.
Fiscal depute John Adams told the court that at 1.30am Mr Milne had tried to kiss a woman, who declined.
Mr Adams said: “A number of witnesses within the bar then saw the accused headbutt the complainer. None of these people saw the complainer do anything to provoke the assault.
“As a result, the complainer fell backwards and struck the back of his head on the tiled floor. Immediately after the assault, the accused left the building.”
Mr Milne was taken to Ninewells Hospital via ambulance where he received treatment to a perforated eardrum and bleeding to the ear. A CT scan showed he also had a skull fracture.
Pluscs was traced and, during his police interview, told officers that he had kissed a woman, left momentarily, and returned to kiss her again.
After kissing her the second time he said he turned and saw Mr Milne standing in his way and headbutted him.
He admitted Mr Milne had not done anything other than stand in his way prior to the assault.
