Parts of the concertina wire at the San Diego border were stolen and sold by Mexican nationals in March. Mexican authorities seized the military-grade wire and returned it to U.S. authorities.
The United States Customs and Border Patrol San Diego Sector (CBP) installed the concertina wire as a preventative effort against the migrant caravan’s illegal border rush back in November, 2018. Now, with Tijuana’s recent spike in crime, pictures of Mexican houses can be seen online reinforced with the stolen wire to keep intruders out.
