Newark fish wholesaler Ocean Seafood Depot was raided yesterday by U.S. Immigrations and Customs Enforcement, allegedly without a warrant, according to reports. Both undocumented workers and U.S. citizens were detained, the agency and the mayor’s office confirmed.

In a statement, Newark mayor Ras Baraka said ICE agents detained lawful citizens during a raid on a local business, calling it an “egregious act.”
