Gardaí have confirmed that a 25-year-old asylum seeker who was found dead at a hotel in Co Monaghan yesterday morning suffered a serious head injury.
State Pathologist Dr Heidi Okkers carried out the post-mortem examination this afternoon, however the cause of death has still to be determined and gardaí are awaiting the results of toxicology and other tests.
It is still not clear whether the man sustained the head injury accidentally from a fall or deliberately, but gardaí say all the resources necessary to investigate his death have been deployed.
The man's death remains "unexplained", they added.
An incident room has been established at Carrickmacross Garda Station, and gardaí have appealed to anyone with information to contact them on 042 969 0190, the Garda Confidential Line on 1800 666 111 or at any garda station.
Detectives also believe the man's body may have been at the gates of the M Hotel on the Kingscourt Road at Lossets for some hours before he was discovered unresponsive yesterday morning.
A member of the public alerted gardaí at around 8am.
The M Hotel provides emergency accommodation for people seeking international protection in Ireland, and those living in the direct provision system.
It is understood it provides 35 rooms for up to 124 asylum seekers.
Gardaí have identified the man, who is originally from Africa, and are liaising with relatives before a decision is made to publicly name him.
They are also investigating if the man's death could be connected to a disturbance at the hotel on Halloween night.
Gardaí were called there but the situation had calmed down by the time they arrived around 10pm.
They believe the man may have been involved in the earlier disturbance.
