The Garda Ombudsman is appealing for information surrounding the death of a man in Dublin last week.
It happened after 11pm on Thursday and ran into the early hours of Friday, on the Old Lucan Road in Palmerstown.
GSOC says the specific location is beside the supermarket and vet hospital at Riversdale Avenue.
It's urging anyone who witnessed any activity, or has video recordings from this time and area to come forward.
In a statement the Garda Síochána Ombudsman Commission said:
"GSOC would like to speak to any witnesses who observed any incident, activity or interactions, including involving members of An Garda Síochána, at this time and location. GSOC would also welcome the provision of any CCTV, dashcam or mobile footage witnesses may have captured.
Anyone with information which may be of assistance is asked to contact GSOC at 0818 600 800 or email@example.com."
