Sheriff’s deputies in Livingston and Tangipahoa parishes led operations netting more than 40 suspects with outstanding drug warrants, representatives said Thursday.

In Livingston Parish, deputies arrested 25 people during an operation that began in the early morning and stretched into the afternoon, said Jason Ard, chief criminal deputy for the Livingston Parish Sheriff’s Office.

The arrests were the result of undercover drug operations going back to the beginning of the year, Ard said.

At least one of those arrests occurred after the Sheriff’s Special Response Team kicked in the door of a suspected crack dealer.

Deputies found $1,800 worth of crack hidden in the siding of an adjacent trailer and a digital scale in the house, Ard said.

Deputies also focused on several prescription drug dealers, Ard said.

As of 4:30 p.m. Thursday, deputies were still working to make arrests on 74 warrants that had been issued for 39 people, Ard said.

There had not been any incidents connected with the arrests, Ard said.

More than $2,500 in oxycodone was recovered during one arrest in Denham Springs, Ard said.

Deputies began arresting people around 7:45 a.m.

Sheriff’s deputies were assisted by the Denham Springs Police Department and Louisiana Probation and Parole agents, Ard said.

In Tangipahoa Parish, deputies rounded up 23 suspects, according to a news release from Sheriff Daniel Edwards.

The effort was a combined effort of the Sheriff’s Office, the Tri-Parish Narcotics Task Force and the Hammond Police Department, Edwards said.

The warrants were the result of an ongoing investigation by the agencies, with assistance by the St. James Parish Sheriff’s Office, Kenner Police Department and the U.S. Drug Enforcement Agency.
