Calais migrants interrupt polar bear's trip to Yorkshire Wildlife Park
A group of migrants who jumped onto the back of a lorry in Calais bound for the UK found some unexpected company onboard - a polar bear.
Nissan, a 22-month-old male, was being moved to Yorkshire Wildlife Park near Doncaster when the four men climbed aboard the truck in slow traffic.
They were described as "shocked" to see the animal, but three of the four remained with the unusual cargo.
French police were alerted and the men were ordered off of the lorry.
Simon Marsh, animal collections manager at the park, said Nissan's transfer from Moscow to Doncaster had gone to plan apart from the issue in northern France.
"There was a slight hiccup at Calais," he said. "Nissan had some unexpected guests in the back of the lorry.
"Obviously he was in a crate, so it was all very safe and secure, but I think they were a bit surprised when they saw a polar bear."
Nissan arrived at the wildlife park in South Yorkshire after his unscheduled overnight visit and staff are preparing to introduce him to the park's two other polar bears, Victor, 16, and Pixel, 2.
Strict welfare regulations were in force throughout the 1,800 mile (3,000 km) journey from Moscow to Doncaster via Frankfurt in Germany, by road, sea and air.
The bears will be introduced over the next few weeks in the purpose-built 10-acre Project Polar reserve designed to replicate their Arctic habitat.
Nissan was born at Izhevsk Zoo, in Russia, on 12 December 2013 and has been moved to the UK as part of the European breeding programme.
