Thai police have issued arrest warrants for two Americans who tried to mail a preserved baby's head, foot and other human body parts to the US, saying the objects were stolen from a Thai medical museum.
The bizarre case has quickly gained international attention, with Thai police asking Cambodian authorities to help locate the men, who travelled to the neighbouring country on Sunday, and the FBI helping with the investigation in the US.
Police questioned Ryan McPherson (31) and his friend, Daniel Tanner (33) in Bangkok over the weekend but released them and allowed them to travel to Cambodia.
New evidence then emerged after their departure, prompting the arrest warrants to be issued on charges of theft, possession of stolen items and falsely declaring items on shipping documents, said police Major General Sombat Milintachinda, the head of Bangkok's police investigation bureau.
"Our evidence indicates that they either stole the body parts, or they bought them from other people," he said. "We have to bring [these men] back for more questioning."
The case of the human body parts emerged over the weekend when parcel delivery company DHL said it scanned three US-bound packages labelled as toys and detected five human body parts. DHL alerted police who tracked down the senders, McPherson and Tanner, and took them in for questioning.
