A Waltham Public Works Department employee has been placed on administrative leave with pay after he was arrested last week in Newton on drug charges.
David Caira, 50, was arrested Wednesday by Newton police on charges of possession with intent to distribute heroin, possession of cocaine, and conspiring to violate drug law.
He was arraigned in Newton District Court Friday, pleaded not guilty and was released on personal recognizance, said MaryBeth Long, a spokeswoman for Middlesex District Attorney Marian Ryan.
Waltham Mayor Jeannette McCarthy said she received a tip about Caira's activity and reported it to Waltham's acting police Chief Keith MacPherson.
"I received a complaint, and notified police chief MacPherson," she said.
McCarthy said there are departmental civil service proceedings in the works, where public works director Michael Chiasson will determine what consequences to impose. The results could include taking away Caira's pay, McCarthy said.
Those proceedings could take a few weeks to get underway, she said.
Caira's job includes driving special public works vehicles, for which he has a specific separate license, McCarthy said.
Although she could not say specifically how long Caira has worked for the city, McCarthy did note that he "is not new."
