Two suspected illegal immigrants were seen climbing from a coach outside a school in Tower Hamlets after it arrived back from a school trip.

Mother Louise Barnes told The Express she saw it all unfold as she picked up her 11-year-old from Cubitt Town Junior School on the evening of Monday, June 22.

It is believed the pair – who police say came from Sudan – boarded the coach at Calais as it brought schoolchildren back from a two-day trip in France.

Ms Barnes said: “They were covered in dirt and just sat next to the fence looking very tired.

“My child and my friend’s children believe they got on at Calais and, seeing the news showing scenes there at the moment, I can easily believe that.”

Due to a ferry strike there is a lot of unrest at Calais and immigrants have been seen jumping on board passing trucks more frequently than normal.

A Met Police spokesman said: “When police arrived the two men had already left the scene. Officers quickly located the men nearby and detained them for illegal entry.

“The two men aged 27 and 23 years were taken to an east London police station where they have been referred to UK Border Agency. Both males are believed to originate from Sudan.”

A Tower Hamlets council spokesman said: “A bus carrying pupils from Cubitt Town Primary School unwittingly carried two stowaways underneath the coach on a return trip from France yesterday.

“When school staff were made aware of the stowaways’ presence, they immediately contacted the police who were quick to arrive and deal with the issue.

“The stowaways travelled below the vehicle and had no direct contact with the children on board. School staff acted professionally throughout and continue to be committed to keeping their pupils safe from danger.”
