Federal immigration agents have been spotted around the state today, including in Portland and Westbrook.

Westbrook police Capt. Tom Roth said his department provided officers to assist immigration agents with an “operation” today in that city, but declined to be more specific.

Immigration agents had not booked anyone at Cumberland County Jail today, as of early this afternoon, according to a jail employee.

An employee at Kon Asian Bistro on Brighton Avenue in Portland, one place where vehicles from U.S. Immigration and Customs Enforcement were seen, said the restaurant would be open for dinner and wouldn’t say whether immigration agents had been at the restaurant or made arrests there.

Chuck Jackson, spokesman for the federal agency’s New England field office in Boston, declined to comment and referred questions to the U.S. Attorney’s office.

Assistant U.S. Attorney Don Clark also declined to comment.

According to media reports, ICE agents were also seen today at the New China Super Buffet restaurant in Lewiston, at a home in Brewer and at two other restaurants, the Twin Super Buffet in Brewer and the Super China Buffet in Waterville.

On Sept. 21, federal immigration agents raided three Mexican restaurants, Fajita Grill in Westbrook and Cancun restaurants in Waterville in Biddeford. Agents arrested eight workers from Mexico and Guatemala, as well as Guillermo Fuentes, owner of Fajita Grill, and his brother Hector Fuentes, owner of the other two restaurants.
