Twenty inmates in Nassau County are under investigation after weapons and drugs were found at a correctional facility in East Meadow

Officials say the raid is part of an operation to clean up the jail under new leadership.

Recently appointed Corrections Commissioner Michael Sposato says he is confident he will be able to keep contraband out of the facility.

"Criminal activity did not end with incarceration but continued behind bars for these individuals," Sposato says. "The raid results further confirm County Executive Blakeman's assessment that new leadership was needed."

Sposato previously lost his sheriff job in 2017 because of inmate deaths and allegations of mismanagement.

The correction officers union told News 12 his appointment is "slap in the face."
