Cops used the gay dating app Grindr to track down and arrest an alleged meth and cocaine dealer in Stuyvesant Town on the East Side last week.

An NYPD source told DNAInfo that 55-year-old Harold Gondrez Jr.'s profile on the app included "coded language that the undercover officer recognized as a possible advertisement for drugs."

Officers raided Gondrez Jr.'s apartment around 6:15 a.m. on July 21st and turned up a "large quantity" of cocaine and meth, according to a department spokesman. The haul included five bags of coke, seven bags of meth, five pipes and $4,000 in cash.

Gondrez Jr. was released without bail following his arrest and is due back in court in September. He's been charged with criminal possession of a controlled substance and criminal possession of drug paraphernalia.

The NYPD has executed a search warrant for the alleged dealer's apartment, and an investigation into the drug sale operation is ongoing. In the meantime, be careful with potential Grindr dates whose profiles use artful euphemisms like "blow" or "smokin" or "want 2 get hi off all these drrruuugggggsss?"
