PHOENIX -- A Maricopa County sheriff's posse has suspended its operations after questions arose over who is responsible for paying for insurance coverage on posse-owned vehicles.
Sheriff Joe Arpaio says the Sun City posse is the only one of his 57 volunteer posses to suspend its operations over the question of liability.
The sheriff's office says the county had previously covered some posse-owned vehicles but that county officials have recently said posse members have until mid-April to get private coverage for the vehicles in question.
The police agency says the issue arose as a result of a policy change by the county.
But county spokeswoman Cari Gerchick says she was unaware of any such changes.
A Sun City posse commander didn't return a message left Monday by The Associated Press.
