According to a report in the Daily News, the deputy inspector made the threatening remarks last June, when 50 Cent was scheduled to attend an NYPD-sanctioned boxing match in the Bronx.
Police say 'the matter is under internal review.'
50 Cent tweeted in part on Sunday, saying: "This guy, Emanuel Gonzales is a dirty cop abusing his power. The sad part is this man still has a badge and a gun."
