Following the incident, the Home Office said: “People should claim asylum in the first safe country they reach and not risk their lives making these dangerous crossings.
“We are continuing to pursue the criminals behind these illegal crossings.
“Police patrols on French beaches and enhanced intelligence sharing between our security and law enforcement agencies has helped to prevent crossings.
“The Government is also returning illegal migrants who have no right to stay in the UK to safe countries.
“In January, new rules were introduced which make asylum claims inadmissible where people have travelled through safe countries to get to the UK through illegal routes.”

Up to £1 million is thought to have been spent by ministers to prevent illegal Channel crossings.
Separate reports claim British armed forces sold France £28 million worth of military-grade equipment in an effort to curb migrants making their way across the English Channel.
In the deal, agreed with Paris last year, the armed forces provided drones, thermal imaging gear, advanced binoculars, radar technology and a fleet of motorbikes to detect trafficking boats.
A source told The Times about how thermal imaging equipment is now being used to detect boats that traffickers hide in sand dunes on French beaches.
In addition, the British-provided military-grade drones fare better in misty conditions than those used by the French previously.
