A suspected bomber was confirmed dead after a series of explosions killed at least 10 in southern China, police said Friday.
Police in Liuzhou city in Guangxi province said they used DNA testing to confirm that 33-year-old local man Wei Yinyong was killed by one of the blasts.
It is unclear when Wei died or why police earlier said they had arrested a suspect surnamed Wei late Wednesday.
Some 18 parcel bombs on Wednesday and Thursday killed at least 10 people and injured 51, the official Xinhua news agency said Friday.
Seventeen explosions occurred between 1:15 pm and 5 pm (0515 and 0900 GMT) near a hospital, a supermarket, a bus station and several government buildings in the Liucheng area, according to state media.
Another explosion hit a residential building early Thursday.
Wei had made homemade time bombs and disguised them as packages, police said.
He then personally delivered and hired other people to deliver the bombs to different locations.
Wei committed the crime to “take revenge on some villagers and institutions that he had disputes with in quarrying business,” the Xinhua news agency cited police as saying.
Explosives and small bombs are regularly used in response to personal or professional disputes in some parts of China in what state media refer to as revenge attacks.
