A convicted killer who assaulted his ‘best mucker’ has been jailed for 20 months at Derry Crown Court.

Sean Anthony Paul Devenney, of Lisdale Mews, pleaded guilty to attempted grievous bodily harm with intent.

The charge relates to an incident in an Eglinton bar on December 11, 2016.

In 2011, 27-year-old Devenney was convicted of the manslaughter of Shantallow man Jim McFadden after a wedding in Redcastle county Donegal and was jailed for four years.

The court was told that since his release from prison, the defendant has become a successful boxing coach and runs his own club in the city.

As regards the latest offence Derry Crown Court heard that Devenney was in a bar with his partner and best friend and his wife.

He had been best man at the injured party’s wedding the year before and they had been ‘best muckers’ for 16 years.

The 27-year-old had a disagreement with his partner and the injured party intervened.

A scuffle ensued and Devenney punched the injured party.

The men were seperated for a short period of time before Devenney attacked the injured party again.

The court heard the 27-year-old hit the man on the head with a glass bottle and continued to punch him.

The injured party sustained a laceration to the back of his head which required three staples, a cut to his left eye and a swollen nose.

Passing sentence, Judge Elizabeth McCaffrey said that offence had been aggravated by the fact that Devenney had assaulted the injured party and the returned and assaulted him again.
