Twenty-three suspected undocumented immigrants were arrested Monday night in Hamburg, according to a Customs and Border Protection official.

The arrests resulted from "a random encounter by agents on a routine patrol in the area," a spokesman for the agency said

The arrests occurred near a 7-Eleven at Southwestern Boulevard and Sowles Road.

"The suspects have been transported to a holding facility where they will be processed," the spokesman said in an email. "The incident is currently under investigation by U.S. Border Patrol."

Law enforcement sources said none of the men arrested is believed to be a serious criminal, and indicated all are likely to be charged administratively, not criminally, after being processed by Border Patrol authorities.

Unlike raids in the past, which resulted in undocumented immigrants charged with crimes in federal court, the men arrested in Hamburg are expected to have their cases handled by immigration authorities.

It was not clear where the men live, if they have families here, where they came from and if they face deportation.
