CBC Radio interview with the guy.
He continues in the radio interview. He went with a ranger and the ranger found a herd, and the baby bison re-integrated. The ranger gave Kassam a ticket for interfering, but said there was no reason to appear in court. Two days later, Kassam gets a call and hears that the calf did not in fact re-integrate, and that he will have to appear in court.
Kassam is also from Africa, and he said the practice there is to scoop up abandoned babies (often left behind by poachers) and to deliver them to local wardens. He didn't know that you couldn't do that in America.
