Tijuana municipal police seized more than 100 pounds of fentanyl and detained two suspects during a raid on a residential property in Colonia Lomas del Matamoros on Tuesday, June 17. The operation also turned up methamphetamine, a handgun, drug packaging materials, and a stolen vehicle, making it one of the larger local seizures in recent months.
Officers Found Fentanyl, Meth, and a Stolen Vehicle at the Property
According to municipal authorities, officers from Tijuana’s Secretaría de Seguridad Ciudadana (the city’s public safety department) were conducting patrol operations in the eastern Lomas del Matamoros neighborhood when they observed suspicious activity at a residence. Upon investigation, they discovered approximately 47 kilograms (about 103 pounds) of fentanyl and a quantity of methamphetamine inside the property.
Police also recovered a firearm, ammunition, digital scales, and materials used for packaging narcotics. A vehicle parked at the location had been reported stolen. Two individuals found at the property were detained and turned over to the Fiscalía General del Estado (FGE), Baja California’s state attorney general’s office, for prosecution.
The seizure took place in a residential area of eastern Tijuana, far from the tourist corridors and border crossing zones most familiar to visitors. Lomas del Matamoros sits in the hillside colonias east of the city center, an area that has seen periodic law enforcement operations targeting drug storage and distribution points.
Tijuana Remains a Key Corridor for Fentanyl Bound for the U.S.
Tijuana’s role in the synthetic drug trade is well documented. The city sits directly south of San Diego, and the San Ysidro port of entry is the busiest land border crossing in the Western Hemisphere, processing roughly 70,000 northbound vehicles per day. That volume of traffic makes the corridor a primary route for smuggling fentanyl into the United States.
The U.S. Drug Enforcement Administration has identified Tijuana as one of the principal transit points for fentanyl produced by Mexican cartels. The Sinaloa Cartel and Jalisco New Generation Cartel (CJNG) both maintain operations in the city, and turf disputes between affiliated cells have driven much of Tijuana’s violence over the past several years. In 2023, Tijuana recorded 1,507 homicides, many of them linked to cartel conflicts over drug trafficking routes.
Mexican federal authorities have stepped up fentanyl interdiction efforts under pressure from Washington. In March 2025, Mexico’s military seized a record 1.4 metric tons of fentanyl in a single operation in Sinaloa. At the local level, Tijuana police and Baja California state forces have carried out a series of smaller but significant busts targeting stash houses and packaging operations within the city.
Fentanyl seizures in Tijuana have increased in frequency over the past two years. In many cases, the drug is stored in ordinary-looking residential properties before being moved to crossing points along the border. The pattern of using residential neighborhoods for storage reflects a deliberate strategy to avoid detection, as cartels rotate locations frequently to stay ahead of law enforcement.
Security Operations in Eastern Tijuana Colonias Have Intensified
The Lomas del Matamoros bust fits a pattern of increased police activity in Tijuana’s eastern hillside neighborhoods. These colonias, many of them working-class residential areas with limited infrastructure, have become focal points for security operations. Municipal and state police have conducted joint patrols and targeted raids in the area throughout 2025.
Tijuana’s municipal police force has been undergoing a reorganization and expansion effort. Mayor Ismael Burgueño, who took office in October 2024, pledged to increase police presence in high-crime colonias and improve coordination with state and federal agencies. The city has also invested in surveillance technology and intelligence-sharing protocols with the FGE.
For residents in Tijuana’s more central and western neighborhoods, including the expat-frequented areas of Playas de Tijuana, Zona Río, and the Rosarito corridor, operations like Tuesday’s raid are a reminder that drug enforcement activity continues at a steady pace across the city. These busts rarely affect daily life in tourist or residential zones, but they reflect the ongoing security dynamics that shape Tijuana’s policing priorities and resource allocation.
The two detained suspects now face state-level charges for drug possession, weapons violations, and possession of a stolen vehicle. The FGE has not released their identities. The seized fentanyl will be cataloged and destroyed under federal protocols. Reporting on Tuesday’s operation was first published by El Imparcial de Tijuana.
