A £60,000 remote-controlled dinosaur robot has gone missing from a Walking with Dinosaurs show in Mexico.
It was the first time an exhibit has been stolen from the show, which has toured worldwide and been seen by more than four million people.
"Only in Mexico! How it happened, we don't know. We don't even know if whoever stole it knows its value," said Karla Arroyo, a spokesman for the show.
Walking with Dinosaurs opened in Guadalajara last Friday, and staff discovered that one of the smaller robots was missing after the show closed that same day.
At around £60,000, the missing 5ft dinosaur is the least expensive robot at the show, which measure up to 42 feet and cost up to £600,000.
Despite the robbery, she said the show did not stop: "Everything went on as usual," she added
