Tourists were ticketed and forced to release a baby bison from the back of their SUV at Yellowstone National Park, NBC News reported.
Two foreign tourists, a father and son duo, were worried that the calf was too cold, according to a witness who snapped a photo of the bison in their vehicle.
Rob Heusevelet, the father of a student on a field trip, told the East Idaho News of nearby Idaho Falls that rangers ordered the men to remove the bison and warned them that they could be in trouble for having the animal. The National Park Service forbids visitors from approaching within 25 feet from large animals.
"They didn't care," Heusevelet told the news site. "They sincerely thought they were doing a service and helping that calf by trying to save it from the cold."
