The trial of a man accused of killing a taxi driver in Dublin in a row over a fare has heard how he drank up to eight pints before throwing a fatal punch.
William Keegan of Pearse House, Pearse Street admits punching the Nigerian driver but denies his manslaughter.
In the early hours of November 21, 2011, William Keegan and taxi driver Moses Ayanwole got involved in a row over a fare.
Before that, the accused had spent eight hours drinking with friends at the Padraig Pearse pub on Pearse Street.
They flagged a taxi just after midnight and Keegan told gardaí that his friends jumped into another cab after Moses refused to carry five people in his.
He got out and Moses followed him up the street demanding some sort of a fare.
At this point, Keegan said he swung around and hit him once in the face. "Just one bleedin' box" is how he described it.
He said he ran home and did not realise the Nigerian native banged his head off the ground after falling backwards.
The 41-year-old, who'd been living in Ireland for 15 years, died in hospital two days later.
Keegan was arrested the day after the assault.
The trial continues before a jury of six men and six women.
