A 26-year-old man who killed a university law graduate with a single punch has been jailed for six years and nine months.
Twenty-seven-year-old Esinkumo Ayabowei, also known as Henry Esin, from Llangefni on Anglesey, was found unconscious outside Peep nightclub during the early hours of Saturday 1st April.
He later died in hospital.
Judge Paul Thomas QC told Kieron Roberts of Penrhyn Avenue, Bangor, that he had been seeking to cultivate a hard-man image and to demonstrate his punching power.
Keiran Roberts, 26, pleaded guilty to manslaughter at Mold Crown Court in September.
The judge at Caernarfon Crown Court found that a case for dangerousness had been made out and added five years to the sentence in which time he will remain on parole.
The court heard Ayabowei was a civil servant and local footballer, married with two young children and was a 'hapless victim'.
The judge said Roberts had gone out that night 'bent on trouble'.
The court also heard a powerful blow had broken his jaw and then his skull was fractured when he collapsed to the ground.
Judge Thomas gave his condolences and sympathy to the family and commended them for their dignity.
Henry's wife paid tribute to him saying 'the world truly is a lesser place without him.'
