Brockton native, businessman and two-time gubernatorial candidate Christy Mihos is under investigation for domestic violence.
Yarmouth Police are looking into two apparent incidents.
The first was in West Yarmouth last July, and the second was in Florida just last week, though no details have been released.
The 62-year-old Mihos owns homes in both places.
Police have suspended his firearms license and confiscated a handgun.
