Gardai investigating the murder of a man at a west Dublin rave at the weekend are renewing their appeal for witnesses.

26 year old James Griffin was fatally stabbed in an industrial park in Parkwest, in the early hours of Sunday morning. He was taken to Tallaght hospital where he was later pronounced dead.

Gardai in particular are appealing to Taxi drivers who dropped or collected people at the unit on O'Casey Avenue between 3 am and 4.30 am on Sunday.
