A man in his 30s died in an incident near Naas in late September.
Gardai are renewing appeals for information in relation to a crash on the M7 in Co. Kildare last month, in which a man in his 30s was killed.
The two-car collision happened on the northbound carriageway at Osberstown, Naas on Saturday, September 25th.
The man was struck while trying to assist with the collision and was taken to Tallaght University Hospital but later passed away.
Officers believe a number of motorists who witnessed the collision have not yet come forward and are appealing for them to contact Gardai at Naas Garda Station on 045-884-300.
