CHICAGO, June 21 (UPI) -- Police and federal agents Wednesday raided a Chicago housing project and other locations searching for fentanyl-laced heroin blamed for more than 60 deaths.
Authorities suspect the fentanyl was illegally manufactured at a drug laboratory in Mexico and added to street heroin nicknamed "lethal injection," "drop dead" and "killer instinct."
The drug has killed hundreds of users in Chicago, Detroit, Philadelphia, Camden, N.J., and other U.S. cities this year.
Scores of law enforcement officers, wearing black bulletproof vests, swarmed the Dearborn Homes on the near South Side after dawn and arrested several of the 48 people being sought for drug trafficking, the Chicago Sun-Times reported.
Drug ring suspects and associates, including a police officer, were arrested, some in suburban towns, officials said.
The fentanyl-laced heroin began showing up in Chicago in February and more than 105 users suffered drug overdoses during just one week in April.
