A former League of Ireland soccer star who stabbed a man during a late-night attack in Finglas, Dublin has been jailed for five-and-a-half-years.

Gardaí in Dublin and Co Louth have arrested six people in connection with the murder of 35-year-old David McGuinness in Tallaght earlier this month.

A 35-year-old man was shot dead in a gangland-style killing last night in Dublin, gardaí said.
