China's former vice-minister of public security, Li Dongsheng, was jailed for 15 years for accepting bribes, a court announced on Tuesday.

Dozens of officials in the government, military and State-owned enterprises have been brought down in a sweeping anti-graft campaign over the past three years under President Xi Jinping.

Li went on trial in Tianjin in October, charged with illegally accepting almost 22 million yuan ($3.5 million) worth of assets, Xinhua News Agency reported at the time.

Authorities also confiscated 1 million yuan in personal assets, China Central Television said on its microblog.

Xinhua said on Tuesday that Li had abused various posts he held since 1996, including one as a deputy head of CCTV.

Listing his crimes, Xinhua said Li "sought improper benefits", including "handling major accident liability" for a person named Zhao Lifu.

Li kept close to 5 million yuan and passed the rest to his brother, Li Fusheng, the news agency said.

Li said in court that he would not appeal, according to CCTV.
