The stream of calls to 911 began on August 31, when the system became overwhelmed with hundreds of fake emergency calls.
Police say Michael Salino, 37, of 169 Van Buren Street in Mastic, used two cell phones to make the bogus calls, which included fictitious reports about fires, motor vehicle accidents, injuries and robberies in different locations in Suffolk County.
Investigators from the county's Seventh Precinct Crime Section arrested Salino on Monday at about 5:25 p.m. near William Floyd Parkway and McGraw Street in Shirley.
Salino was charged with six counts of falsely reporting an incident in the second degree and 25 counts of falsely reporting an incident in the third degree. The charges are felonies and misdemeanors, respectively.
Police say aside from the 31 calls he was charged with, Salino may have placed as many as 300 phony emergency calls. The investigation is ongoing.
Salino was held overnight at the Seventh Precinct police station jail and is set for arraignment at the First District Court in Central Islip on Tuesday.
