A team of accident investigation experts have launched an inquiry into an incident on a P&O ferry that saw a number of lorries topple over.

The ferry was making a crossing in high winds between Larne and Cairnryan on Tuesday morning when a major emergency response was launched after six lorries tipped onto their sides at around 7.40am.

The Marine Accident Investigation Branch confirmed it was launching an investigation on Wednesday.

A number of passengers were unable to disembark the ferry after the incident, which damaged cars and boats on board.

One lorry driver told STV News: "It felt like we hit a big wave and then there was a massive bang."

The port was closed for most of the day.

A Marine Accident Investigation Branch spokesperson said: "Having reviewed the initial evidence following the cargo shift on board the ferry on Tuesday, we have opened an investigation."
