Organizers of the Mexican tour of the "Walking With Dinosaurs" show say someone has walked off with a robotic baby Plateosaurus.

Spokeswoman Karla Arrollo says the 1.5-meter (5-foot), remote-controlled dinosaur worth $25,000 disappeared after Friday's performance. Police say they are investigating the alleged theft.

Arrollo says the show _ which features 10 species of large, mechanized dinosaurs lumbering across an arena stage _ will continue touring.

But organizers had to redesign the first scene, which originally involved a larger dinosaur devouring the baby.

She says organizers have also requested increased security to protect the prehistoric performers when the show opens in Mexico City on Wednesday.
