Fugitive ex-soldier, who escaped U.K. prison on bottom of truck, caught while riding bike

A former British soldier facing terrorism charges who snuck out of a London prison on a food delivery truck was captured Saturday, police said.

Daniel Abed Khalife was nabbed while riding a bicycle along a canal path west of London after a four-day manhunt.

Khalife escaped from the Wandsworth Prison kitchen on Wednesday and got outside the gates by strapping himself to the bottom of a catering truck.

The 21-year-old was awaiting trial on charges of violating Britain's Official Secrets Act by gathering information "that could be useful to an enemy" and planting fake bombs at a military base. He was discharged from the British army after his arrest earlier this year and had denied the allegations. His trial is set for November.

Governing Tories face criticism

The breakout ignited a storm of criticism as political opponents linked the escape to years of financial austerity by the United Kingdom's governing Conservative Party.

The government said an independent investigation would determine how Khalife escaped the medium-security prison that opened in 1851 during the reign of Queen Victoria.

"We need answers about how on earth a prisoner charged with terror & national security offences could have escaped in this way," Yvette Cooper, a Labour Party MP, wrote on social media on Saturday.

British Prime Minister Rishi Sunak thanked the police and public and said the inquiry would get to the bottom of how Khalife got away.

The escape prompted extra security checks at major transport hubs, particularly in and around the Port of Dover, the main boat crossing from England to France, and at one point led to the shutdown of a major highway.

Unclear if reward claimed

London counterterror police had offered a 20,000-pound ($25,000 US) reward for information leading to Khalife's arrest. It was not immediately clear if anyone was in line for the reward.

Police on Friday had announced a breakthrough in the search after a witness reported seeing Khalife at a busy intersection near the prison shortly after the escape.

Metropolitan Police's counterterrorism commander Dominic Murphy wouldn't say if the sighting was confirmed by surveillance cameras, but London has one of the most robust security camera networks in the world, and any footage could have helped track his whereabouts.

"In terms of the investigation, it really gathered momentum yesterday afternoon, with a number of calls from the public, but really took a different course last night, when we did an intelligence-led search in the Richmond area in the early hours of this morning," Murphy said.

"Whilst we didn't find him at that search, while we were at that search, we had a number of calls from the public over the next hour or two, giving us various sightings of him."

Search efforts in Chiswick

Police had received reports that Khalife was seen in the Chiswick area of west London, and officers descended there on Saturday morning, with police cars and vans swarming the area and helicopters hovering overhead.

Paul Wade said he opened his curtains to find five police officers outside his home.

"They said, 'I expect you know why we are here,'" he said. "They were checking everybody's gardens."

But Khalife was nowhere near there when a plainclothes officer ultimately made the collar in the late morning, Murphy said.

Khalife was pulled off a bicycle along the canal near the community of Northolt, about 16 kilometres from where he escaped.

Murphy said he was co-operative when arrested. Khalife now faces additional charges of being unlawfully at-large and being an escaped prisoner.
