A man in Xiamen, Fujian Province, was recently arrested for causing a bomb hoax in the building where he lives.
On being questioned, Cai said the oldies in the building created a lot of noise doing early morning exercises in the lobby.
On Aug 10, Cai phoned the security guard of the building, saying he had planted a bomb in the lobby. The guard immediately phoned the police, who evacuated the building, only to realize it was a hoax.
