A federal grand jury is now probing allegations related to various procedures and treatment given to various current and former San Bernardino County officials at the county-owned and operated Arrowhead Regional Medical Center (ARMC).

Sources tell that several federal grand jury subpoenas requesting the appearance of individuals and the production of documents have been issued.

ARMC sources have become increasingly tight-lipped on the matter in last week.
