Matthew Sheridan has been named as the Galway medical student whose sheep Halloween costume set on fire on Wednesday night.

The 21-year-old, who studies at the National University of Ireland, Galway, is in a critical condition in hospital after suffering from 80 per cent burns. He has now been moved to St James's Hospital in Dublin.

Sheridan's sheep costume set on fire in the Halo nightclub in Galway. Police are now investigating the incident.

Since being hospitalised, friends and other well-wishers have been posting messages of support on Twitter.
