An aide to Massachusetts Gov. Maura Healey was arrested for cocaine trafficking after investigators intercepted packages with the drug slated to be delivered to a state office building where he worked, prosecutors said. 

LaMar Cook, 45, of Springfield, pleaded not guilty during his arraignment Wednesday and was ordered held without bail pending a court hearing, Boston.com reported. 

In addition to the drug charge, Cook is also charged with illegally owning a firearm and ammunition.

Cook served as deputy director of Healey’s Western Massachusetts office, according to an archived staff directory. A spokesperson for the governor’s office said state officials fired Cook “effectively immediately” after learning of his arrest Tuesday, Boston.com reported. 

“The conduct that occurred here is unacceptable and represents a major breach of the public trust,” the spokesperson said. “This criminal investigation is ongoing, and our administration will work with law enforcement to assist them in their work.”

Authorities have seized 21 kilograms of cocaine, including eight intercepted Saturday during a delivery operation at the Springfield State Office Building, the DA’s office said. 

Investigators searched Cook’s former office Monday night. Cook was arrested Tuesday while in his car in Springfield. 

The investigation stemmed from two prior drug seizures. Authorities intercepted and searched two suspicious packages at Hotel UMass (University of Massachusetts Amherst) in Amherst on Oct. 10 and found about 13 kilograms of suspected cocaine.
