Hartford — City police said they arrested 48 people for narcotics, firearms and other offenses last week as part of a crackdown on drug trafficking following a series of deadly shootings.

Lt. Aaron Boisvert, a spokesperson for the Hartford Police Department, said Saturday that the agency's Vice and Narcotics Division also served 29 arrest warrants and executed nine search warrants across the city as part of the effort.

The division "conducted a week of city-wide operations and warrants, targeting areas that have had recent incidents of violence, including shootings, as well as targeting known individuals associated with drugs and violence," Boisvert said.

In all, officers seized about $139,000 in cash, five firearms, 738 grams of fentanyl, 595 grams of cocaine, 121 grams of crack-cocaine and seven pounds of marijuana, Caruso said. He noted the division also worked prostitution details.

The enforcement action took place after four people were killed and three others were wounded last week in the three separate shootings.

On Saturday, two people, including a 17-year-old girl, were fatally shot after a shootout erupted following a home invasion on Maple Avenue. On Monday, a woman was fatally shot at her Oakland Terrace home in what police have characterized as a domestic violence incident. And on Tuesday, a bystander was killed and another was critically wounded in a botched drive-by shooting outside a Barbour Street pizzeria.

Police did not name any of the arrested individuals and did not indicate if any of the defendants are linked to the recent shootings. Boisvert said the department was assisted in the operation by the FBI, DEA and the state Department of Consumer Protection's Drug Control Division.
