According to the Pueblo Chieftain, the undercover detective was in a cellphone store speaking to a clerk when a man came in demanding to know why the detective had so many phones and accused him of being a drug dealer on Monday. He demanded the detective "give him the drugs," according to the paper.
The detective then turned the tables on the impersonator. He showed the man his own law enforcement credentials and advised the man he was under arrest for suspicion of impersonation of a peace officer.
Authorities say Roland Herrera was taken to jail.
