WASHINGTON — Attorney General Eric Holder told Congress "several people" were arrested for immigration violations in the Times Square case.

In describing the development at a House Judiciary Committee hearing, the attorney general said the arrests came as investigators looking into the bombing attempt executed search warrants at locations he did not specify but said they were in the Northeast.

Holder said the latest action came this morning and was "the product of evidence gathered in the investigation" of the Times Square bombing attempt.

A Justice Department spokesman said earlier that two people are in federal custody after search warrants were issued in connection with the Times Square bombing investigation.
