NEWARK, N.J. (AP) — Newark Mayor Ras Baraka briefly returned Tuesday to the gates of the federal immigration detention center where he was arrested last week on trespassing charges.

Baraka has clashed with federal immigration officials ever since the detention facility, privately owned by the GEO Group, opened. Friday’s arrest was a culmination of the back-and-forth, with Newark officials repeating that the owner has not cooperated with local code inspectors.
