El Paso police investigators have arrested 15 people in a yearlong investigation into a mail-theft ring, officials said Monday.

Detectives have identified 37 victims of fraud linked to documents stolen from mail from homes and community mailboxes since December 2016, police said.

An investigation by the police Financial Crimes Unit continues and detectives suspect there could be more victims, officials added.

The arrests have taken place over the past year and additional arrests and charges are pending, officials said.
