Protesters are gathering outside the Philadelphia headquarters of the federal Immigration and Customs Enforcement agency Wednesday morning.

The gathering comes after more than two dozen people were arrested outside the ICE building in early July.

Protesters who camped out overnight called for abolition of the agency, an end to family detentions and closure of a detention center in Berks County. They also want city authorities to stop sharing arrest and court information with the agency.

A police representative says about 75 protesters had blocked the entrance to the ICE headquarters building, refusing to allow anyone to enter or exit.

Police say after several warnings, 29 arrests were made. Those arrested were issued citations for failure to disperse and then released. Two people had minor scrapes and bruises, and one was taken to a hospital for treatment.
