LOS ANGELES – An immigration activist who sought refuge inside a Chicago church for a year was arrested in Los Angeles on Sunday afternoon after taking her campaign on the road.

Elvira Arellano was arrested about 5:15 p.m. EDT by law enforcement officials after leaving Our Lady Queen of Angels church in downtown Los Angeles, said Emma Lozano, an adviser who was there during the arrest.

After talking to news media inside the church, Arellano and her supporters got into their van to head north to San Jose, where she was scheduled to speak at another church, Lozano said. Moments after they got in the van, an unmarked vehicle stopped them.

The driver of Arellano’s van, Roberto Lopez, poked his head out of the van because he wanted to see why they were being blocked. Several other unmarked vehicles surrounded their van.

Agents came out of the cars screaming for her to get out, Lozano said. Her 8-year-old son, Saul, started to cry, and Arellano said to everyone in the car, “Calm down. Don’t have any fear. They can’t hurt me.”

Then she turned to the people who were about to arrest her and she said, “You’re going to have to give me a minute with my son,” Lozano said. She spent time with her son in the car, and then surrendered.

It was over in less than two minutes. She was arrested on Main Street, near Our Lady Queen of Angels, where Arellano slept Saturday night and where she’s held several press conferences Saturday and Sunday.
