MIGRANTS scrambled on board a ferry and scaled the funnel after breaking into the dock area at Calais.
About 100 people stormed the port on Saturday evening in a bid to get to the UK, with many managing to board the Danish-operated DFDS Calais Seaways.
A total of 63 were arrested, French media reported.
The incident caused delays to ferries arriving from Dover and leaving France with the port being closed for about an hour.
One traveller, Matt Perry, tweeted: ‘Currently sat on a P&O ferry outside Calais as captain say it’s closed due to over 100 immigrants storming the port.’ Charlie Elphicke, Conservative MP for Dover, posted on Twitter: ‘How were migrants able to storm a DFDS ferry at Calais? Thoughts with the crew who must have had a frightening experience. Seems a very worrying security lapse.’
President of the Hauts-de-France region Xavier Bertrand wrote on social media: ‘We need to strengthen our security forces on the eve of #Brexit.’
Eleven suspected migrants were also detained at a lorry park in Ashford, Kent, on Saturday. The group, who were handed to immigration officials, claimed to be Eritrean, the Home Office said.
