The alleged members of two rival gangs are back on the streets of Suffolk County after last month's sweeping raids failed to render indictments.

As News 12 reported, eight people were arrested at 90 East Smith St. in North Amityville on Feb. 17. Authorities confiscated guns, ammunition, drugs, drug paraphernalia and cash. A search warrant was also executed on Feb. 19 at 58 Miller Ave. Five people were arrested there.

At the time, Suffolk's police commissioner said that authorities "recovered a ton of evidence."

Police say less than a week after the arrests, one of the defendants, William Montgomery, was released. They say he recently stabbed two people at a store in Bay Shore.

Former Suffolk detective and current Suffolk Legislator Robert Trotta says District Attorney Tom Spota's handling of the case is "preposterous."

A spokesperson for Spota places the blame on the police department. He released a statement reading in part, "the police investigation did not establish legally sufficient evidence to present the case to a grand jury within the timeframe permitted."

Trotta disagreed, citing the guns and drugs that were recovered from the raids.

"Those are invoiced almost immediately. Having been a detective for 25 years, I know the process," says Trotta.

A spokesperson for the Suffolk Police Department had no comment about this report.
