Li Shuangjiang, 74, built his reputation in past decades by singing popular patriotic songs, according to official Xinhua news agency.
The five men are now in criminal custody, the report said.
It is not the first time that junior Li has gotten in trouble.
In September 2011, Li, then 15-year-old, was caught driving an BMW without a driving license or car plate after he viciously attacked a couple following a traffic dispute.
The teenager spent a year in a juvenile camp for re-education before being released in September 2012, official media reported.
