(AP) Police were trying to determine Tuesday whether they were the victim of a hoax after the body they thought they found at a seaside resort was actually a life-sized doll.

Investigators found what seemed like a body wrapped in a sleeping bag in a forest in Izu City, a seaside resort in central Japan, after an anonymous caller reported seeing it, a Shizuoka prefecture spokeswoman said on condition of anonymity, citing department policy.

Investigators never actually looked inside the sleeping bag and brought it back to the city police station for a post-mortem examination, the spokeswoman said. Apparently no one doubted a human body was inside until a medical examiner unwrapped it and found the doll, she said.

The Asahi newspaper said the doll was sophisticated and life-sized and wore a brown wig, a blouse and a skirt.
