Militia man who has been detaining immigrants at New Mexico border arrested

Authorities say a New Mexico man belonging to an armed group that has detained Central American families near the U.S.-Mexico border was arrested Saturday on a criminal complaint accusing him of being a felon in possession of firearms and ammunition.

The FBI said it arrested 69-year-old Larry Mitchell Hopkins, of Flora Vista, in Sunland Park. New Mexico Attorney General Hector Balderas said Hopkins was a member of the group that had stopped migrants.

FBI spokesman Frank Fisher told The Associated Press that Hopkins was in custody but said no additional information would be released until after Hopkins has an initial appearance Monday in federal court in Las Cruces.

It's not immediately known whether Hopkins has an attorney who could comment on the allegations.
