Besides the brothers, three members were also sentenced to death, five were sentenced to death with a two-year reprieve, four to life imprisonment and 22 to imprisonment for different terms.
Three former civil servants among the accused -- Liu Xuejun and Lyu Bin, former police officers, and Liu Zhongwei, a former prosecutor -- were sentenced to 16 years, 11 years and 13 years in prison respectively for harbouring Liu's organisation and taking bribes.
