DC Chervinko says the arrest is related to the theft of department-issued funds and falsification of official financial documents. Knuckles bonded out of jail Friday afternoon. He also resigned from the department.
Chief of Police Todd Walker released a statement that the incident was "disheartening," adding, "whenever a police officer commits criminal misconducts, jeopardizes the agency's integrity and violates the public trust, it will be dealt with by my administration swiftly."
The case is still under investigation.
