Twelve protesters were arrested Friday afternoon after allegedly blocking access to the Lower Buckeye Jail near 35th Avenue and Lower Buckeye Road in Phoenix, authorities said.
The protesters, who have been vocal in their opposition to Arizona's immigration law, were reportedly trying to stop a crime-suppression sweep run by Sheriff Joe Arpaio's office, the Maricopa County Sheriff's Office said.
The road was cleared as of 4:45 p.m., officials said.
Salvador Reza, the leader of a group called Puente, was among those arrested, according to Puente spokeswoman Opal Tometi.
On Thursday, at least 50 protesters were arrested after allegedly blocking a public thoroughfare at Fourth Avenue Jail in Phoenix. Reza was arrested at Thursday's protest as well.
