The number of those hospitalized with serious illness is “constantly rising,” 追加しました.
Provincial security forces detained some people suspected of selling the drug after the first deaths occurred on Wednesday.
Some local media outlets reported that the cocaine had been “cut” with a toxic substance, likely by a drug gang looking to reduce costs amid a turf war with rival groups.
“We are waiting for the laboratory results and the results of the investigations into the people who have been detained,” Sergio Berni, the province’s security minister, told local television.
Reuters could not immediately reach the police and courts for further information.
The local government of Tres de Febrero said in a statement it was aware of people falling seriously ill due to “allegedly adulterated cocaine” and was working with emergency services and hospitals to prevent more deaths.
It urged people to discard any drugs bought recently, especially those with symptoms of confusion, convulsions or loss of consciousness.
“This isn’t a normal investigation,” San Martin prosecutor Marcelo Lapargo told local news outlet La Naction+, citing expedited police raids aimed at removing all the tainted cocaine.
“What mattered most today was to stop the sales to prevent further deaths.”
