Massachusetts State Police arrests follow the same constitutional rights as local arrests. Your friend will be booked at a state police barracks and arraigned in Wrentham District Court (or Norfolk Superior Court in Dedham for felonies). State troopers may coordinate with federal immigration authorities, so a lawyer should be involved at the earliest opportunity. Call Attorney Rory Munns at 401-573-2265 — coordinating Massachusetts criminal defense and immigration consequences in parallel matters.
