Video recordings on social media of a weekend brawl on a boat are believed to show an incident at a Sunday raft-up off Morgan’s Point, according to police.

A spokesman said last night that its circumstances were “unclear”. One film shows a boat packed with revellers before a fight breaks out between at least two men.

Three people on the boat were seen to fall overboard, to the apparent laughter of onlookers on a nearby vessel, from which the fight appeared to be filmed. Police asked for witnesses to contact the main police number at 295-0011.
