Lei was allegedly blackmailing his ex-girlfriend with a sex tape of the pair, so she reported him to authorities, South China Morning Post reported.
When officers searched his home – which resembled a police station – for the tape, they found police and military uniforms, tools including handcuffs and stun guns, as well as forged documents.
Report said Lei would impersonate a police officer and charge his victims to "help fix their problems".
