Gardaí release four men questioned over Dublin pub murder

Gardaí in Dublin have released four men arrested earlier this week in connection with the murder of 42-year-old James Curran.

Mr Curran died after being shot in the head at the Green Lizard pub on Francis Street on April 3.

Gardaí believe the killing was related to a personal dispute.

A man and woman who were arrested in connection with the murder were also released without charge earlier this month.
