Police trying to understand a bizarre sequence of vandalism at dozens of religious sites involving a substance resembling cooking oil said Tuesday that a surveillance camera at a temple had caught images of a man behaving oddly.

Investigators said the scene was caught at the main building of Shigisan Chogosonshi-ji Temple, better known as Shigisan, in the town of Heguri, Nara Prefecture, in late March. A similar individual appears in security camera footage recorded at other sites.

The man is wearing a hoodie and has a camera around his neck, according to the sources and the temple. He is seen holding his hand above the bottom part of a coin offertory box. But police said the image was recorded against the sun in the early evening and lacks clarity.
