Seven men have been arrested after a 24-year-old man from Northern Ireland was attacked in Liverpool.
Emergency services were called to Bold Street, close to Central Station, just after 01:00 BST on Saturday following reports that a man was unconscious on the ground.
The man was taken to hospital where he is being treated for serious head injuries, according to police.
Police said he was in a critical but stable condition.
He is believed to have been visiting Liverpool with family at the time of the attack.
A 40-year-old man from Pontypridd was arrested on suspicion of assault and possession with intent to supply Class A drugs.
Six other men from South Wales, aged between 33 and 41, from Neath, Bridgend, Newport and Talbot Green have also been arrested on suspicion of possession with intent to supply Class A drugs.
It’s currently not known what the group of Welshmen were doing in the city of Liverpool but the suspicion is they were trading drugs to be taken back to their Welsh towns to be sold on the streets when a fracas broke out over a drug-related argument.
Merseyside Police Det Ch Insp Paul Parry said the investigation was ongoing.
He appealed to anyone who witnessed the incident to contact the police.
