Dozens of protesters shut down a busy intersection in downtown Buffalo Thursday afternoon, calling for justice for migrant families.

A large group of activists with the Western New York Peace Center took over the intersection of Delaware and Chippewa — where the local office of the U.S. Immigration and Customs Enforcement Agency is located.

Organizers of the Close the Camps rally say the government's immigrant detention centers are poorly run, inhumane and need to be shut down.

Buffalo police say nine people were arrested.

Mayor Byron Brown says the officers' actions were appropriate.

Spectrum News has learned police were called because people were blocking traffic.

“99 percent of the time they organize with the police department, we’re aware of what they want to do, and we help them accomplish their mission. When those protesters decided to stomp on the rights of their fellow community members that’s when we made the decision to make these arrests and get the streets back open,” said Buffalo Police Captain Jeff Rinaldo.
