It is estimated that the disruption to traffic caused by the incident cost Eurotunnel – the Channel Tunnel operator – some £45,000 in lost revenue. Speaking to MailOnline, Tony Smith, former head of UK Border Force, said: 'The Channel Tunnel is a critical part of our national infrastructure. Shuttles, Eurostar and freight trains travel at up to 100mph along the Channel Tunnel line and pose an immense danger to anyone walking in the Tunnel. A spokesman for Eurotunnel said: 'A person was detected inside the Channel Tunnel and taken into custody by the French Authorities. A Sudanese migrant who walked the length of the Channel Tunnel from France in 2015 was eventually granted asylum in the UK a year later.
