Police have detained a local man over a series of deadly blasts that struck near a provincial headquarters of China's ruling Communist Party, state media reported Friday.

The apprehended suspect was named as Feng Zhijun, a 41-year-old ex-convict and resident of the city of Taiyuan where the explosions took place, the state-run Xinhua news agency said, citing Shanxi province's Public Security Department.

Feng was captured at 2:00 am Friday (1800 GMT Thursday) and has admitted to the crime, according to Xinhua.

No details were immediately available regarding a potential motive for the attack, which killed one person and wounded eight others Wednesday morning near the party provincial commission in Taiyuan.

Self-made bombs were found in Feng's home and car, Xinhua said, citing police.

Large metal ball bearings and circuit boards were found at the scene of the multiple blasts on Wednesday morning, suggesting the use of home-made devices intended to inflict maximum damage.

The incident took place a little over a week after a fiery attack in Beijing's Tiananmen Square that killed three tourists and wounded dozens at the symbolic heart of the Chinese state.

Beijing described the Tiananmen incident as a "terror attack" carried out by members of the Uighur minority from northwest Xinjiang with links to a separatist group called the East Turkestan Islamic Movement.
