A British individual, identified as Craig Sturt, 46, reportedly traveled on a flight from London to New York City without a passport or plane ticket.

According to the New York Post, Sturt is accused of slipping through Heathrow Airport’s security checks without presenting any documents before boarding a British Airways flight to John F Kennedy Airport, again without having his ticket checked.

The 46-year-old allegedly boarded and found a seat on the fully booked international flight because some passengers had missed their connection at the airport. He was arrested after failing to provide a valid means of identification when customs authorities stopped him at a checkpoint.

He was arrested on Christmas Eve and escorted back onto a returning flight to Heathrow. He was charged with Obtaining Services by Deception, Being Unlawfully Airside, and Boarding an Aircraft without permission. The suspect was expected to appear before the court.

Upon his return to London, Sturt was taken to a hospital in Reading, although the reason is unclear. However, Sturt managed to escape the authorities and was reported missing on January 25.

Thames Valley Police issued an arrest warrant against Sturt after he was reported missing.

“The 46-year-old is 6ft, slim, with short dark brown hair. When he was last seen, he was wearing a gray jacket, top, black jogging bottoms, and white trainers,” The appeal reads. “He was last seen in Reading but is from Slough and also has links to Heathrow and Tottenham Court Road in London.”

The Metropolitan Police took over the investigation as of January 31.

“We continue to work with all our partners to review and enhance the already robust security measures in place which are kept under constant review by the wider security partnership,” a rep of the Metropolitan Police said.

Sturt’s brother, Lee Smith, told the reporters that he couldn’t believe his ears when police contacted him to say they were hunting his brother.

“It’s ridiculous this could happen,” Smith said. “If Craig, with a troubled past, could dodge security then presumably anyone else with sinister motives could do the same. Heads should roll. How has this been allowed to happen?”
