Bronx Heroin Bust: NYPD, Special Narcotics Prosecutor's Office Raid Two Lucrative Dope Mills (PHOTOS)

A two-week NYPD investigation led to a raid of two lucrative heroin mills in the Bronx, and resulted in the arrests of 11 people.

The two factories-- located at 2287 Loring Place in University Heights and 1694 Selwyn Ave. in Mount Eden-- were producing roughly three kilograms of dope a week. Kati Cornell, a spokeswoman for Special Narcotics Prosecutor Bridget Brennan, told The Huffington Post that each kilo could fetch around $240,000 on the street.

"This was a significant operation," Cornell told The Daily News. “The profit margin is huge with heroin. They could have been making millions."

A law enforcement source said detectives uncovered 24,000 glassine packets of heroin during the raid, one-third of the amount the factories were thought to produce per week.

The packets were labeled with names like Hot Sauce and Lady Blue.

The heroin, imported from Colombia, was manufactured and packaged at the two Bronx facilities, unbeknownst to neighbors, and distributed throughout Manhattan and New Jersey.

Among the 11 arrested, according to the Daily News, was 40-year-old ringleader Edulcido Genao.
