A New Jersey police dispatcher, a retired detective and a correctional officer are all facing charges in a large-scale drug investigation, prosecutors announced Monday. 

The said Ileana Hernandez, 56, Thomas Mannion, 60, and Marquis Santiago, 33, were arrested last week, along with four other suspects. 

Hernandez is a dispatcher with the West New York Police Department, Mannion is a retired detective of the department and Santiago is a correctional officer with the county, prosecutors said. 

They're accused of taking part in a drug operation, allegedly led by Alfredo Diaz, of Union City. 

More than 4 kilos of cocaine found at production facility, prosecutors say

Prosecutors say they searched multiple locations on July 17 and discovered a narcotics production facility. 

They say they seized more than 4 kilograms of suspected cocaine, worth a street value of over $150,000, as well as two handguns, seven vehicles and more than $70,000 in cash. 

Hernandez was charged with conspiracy to distribute cocaine, along with official misconduct. Mannion was also charged with conspiracy to distribute, and Santiago was charged with conspiracy to possess a controlled substance. 

Diaz, meanwhile, was charged with leading a narcotics network and a slew of other offenses. 

Three others -- Edwin Martinez, Daniel Diaz and Cristian Cortez -- were also charged in the case. 

Three of the suspects face possession with the intent to distribute within 1,000 feet of a school. 

Prosecutors did not provide any further details on the workings of the alleged operation.
