Several officials who participated in the illegal underground "Tibetan Independence" organization, provided intelligence to the Dalai Lama clique and assisted activities that would harm national security, were put under investigation in 2014, authorities in the Tibet Autonomous Region said Tuesday.

A total of 15 officials were punished by the Communist Party of China (CPC) for violating Party and political discipline in 2014, said Wang Gang, an official with the Party discipline inspection commission of Tibet.

Six "typical" cases of Party members and civil servants violating discipline have been announced in Tibet and 45 officials who abandoned their positions and neglected their duties have been severely punished, said Wang.

Some officials failed to take a firm stand on issues related to the Tibet question and some grass-root officials in the region were found to be seriously corrupt, said Ye Dongsong, head of an inspection team of the CPC discipline commission in November 2014. Ye suggested that the Tibetan regional government focus on neutralizing separatists and maintaining social stability, cracking down on corruption and strictly monitoring projects in the region.

Statistics show that the Tibetan discipline inspection department has received 1,494 reports about misbehaving officials from local residents in 2014, an increase of 131.7 percent year on year. Of these cases, 329 cases have been investigated, an increase of 161.1 percent since 2013, according to the China News Service.

A total of 240 people have been dealt with for breaches of the "eight-point" anti-bureaucracy and formalism rules issued in 2014 and 138 of them have been given Party punishment.
