Danbury police assisted federal Immigration and Customs Enforcement (ICE) agents Thursday, who arrested illegal immigrants in Danbury.

"We did assist them," said Danbury Police Department Public Information Officer Thomas Wendel.

Danbury has signed an agreement with federal immigration authorities in September 2009 that gave training on immigration enforcement to two Danbury officers. People in the community feared this arrangement would lead to widespread sweeps of people on the streets, while city government officials said it would be applied to people who engaged in crimes in the U.S.

ICE spokespeople could not be reached for comment Thursday.

Wendel said he didn't know how many people were picked up.

He said from what he understood, some people were picked up and taken to Hartford. Some people were picked up and released. He said in these events, ICE officials are in charge and they take responsibility for releasing any specific information.
