Thousands of doses of opioids seized

THOUSAND OAKS — Ventura County Sheriff’s Detectives investigating the local operations of an alleged Mexico-based drug trafficking organization arrested an alleged vendor in a Newbury Park parking lot this month.

Prior to the arrest, authorities determined that the group allegedly distributed bulk and user quantities of the powerful synthetic opioid fentanyl as well as heroin, cocaine, methamphetamine and counterfeit pills containing fentanyl. The organization’s activity in Ventura County is primarily in the Simi Valley, Moorpark and Thousand Oaks, officials said.

On April 20, narcotics detectives arrested a 32-year-old Los Angeles County man in a public parking lot on the 1000 block of Academy Drive, believing he was actively delivering drugs.

During a probable cause search for the suspect and his vehicle, authorities reportedly seized over a pound of methamphetamine, over 6 ounces of fentanyl, 2 ounces of black tar heroin, 600 counterfeit oxycodone pills allegedly mixed with fentanyl, 3 ounces of cocaine and a large amount of cash.

Sheriff officials said the opioids seized totaled more than 320 grams, the equivalent of about 8,300 doses. Fentanyl can be deadly in amounts as small as 0.25 milligrams, officials said, meaning the amount seized could result in several thousand fatal overdoses.

The suspect was released from jail without charges being filed on Saturday.
