An illegal migrant who broke free from a Los Angeles detention facility with help of anti-ICE activists was caught — while apparently wearing a $1,700 Louis Vuitton T-shirt.

Anti-ICE activists helped British national Ahmed Mohamed escape as he was being transferred to a detention center in downtown Los Angeles last Tuesday, The Post previously reported.

Mohamed, who has a rap sheet including charges of narcotics and weapons possession, was shackled as contract guards lined him up with several other detainees before walking them into the ICE detention center for processing.

A masked man was seen helping Mohamed escape when the guards weren’t looking, Homeland Security sources said. The migrant was then loaded into a waiting van with the help of the protesters.

On Friday, ICE agents in San Diego “swiftly apprehended” the escape artist at an undisclosed location, the agency said in an Instagram post showing the cuffed migrant wearing the designer shirt.

“Great work by HSI San Diego in reuniting Ahmed with his handcuffs,” an Instagram post from ICE read.

He was on the run for about three days before being caught.

Mohamed is now charged with escaping from confinement.

The detention facility was at the center of anti-ICE riots that broke out in June, when rioters hurled concrete blocks at the feds and shut down major highways in an attempt to stop President Trump’s mass deportation raids.

The protests kicked off after Homeland Security agents raided a Home Depot in the Los Angeles suburbs — and flared for several days thereafter.

Trump later deployed 4,000 National Guard troops and 700 Marines to the City of Angels to control the chaos.

California’s lefty Gov. Gavin Newsom sued the Trump administration over the deployment, arguing that it exceeded his authority and ignored the 10th Amendment by calling up the Guard under a federal law intended to address an “invasion” or “rebellion.”

Trump has made cracking down on sanctuary jurisdictions — like Los Angeles — a major priority for his mass deportation effort.
