A 41-year-old man has been arrested in the North in connection with the ongoing investigation into the murder of Kevin McDaid in Derry.
Mr McDaid (49) was killed yards from his home in Coleraine nine days ago when violence flared after a 40-strong Loyalist mob stormed into the area after Rangers beat Celtic to the Scottish Premier League.
A PSNI spokeswoman said the man was helping police with their inquiries this evening.
Nine people have been charged in connection with Mr McDaid's death. Six of them are charged with murder.
