GREENFIELD, Wis. (CBS 58) — This week, the City of Greenfield's mayor filed a statement of charges against Police Chief Jay Johnson, calling for his removal.

Those charges were heard in front of Greenfield's Police and Fire Commission on Thursday night. The commission accepted the charges and moved toward a formal hearing.

The investigation is more than a year old, and Johnson has been on paid administrative leave since last April.

CBS 58 obtained the chief's body camera footage from that time, when he was told about the investigation into his alleged misconduct during a meeting with Greenfield's mayor and other officials.

"I have never been so insulted in my life," Johnson can be heard saying while denying accusations against him.

Johnson is currently facing multiple criminal charges, including four felonies.

Last year, he reportedly directed a member of his department to put a department-owned surveillance camera outside his home because he was "in fear for his safety" during his divorce, despite being explicitly told by the city attorney not to.

The city also began investigating concerns in the workplace, from creating a hostile work environment to berating a union employee — which Johnson previously denied.

He did, however, plead guilty to remotely accessing his personal cellphone while it was in police possession and resetting it to destroy evidence.

"I know my rights. I want an attorney right now because what you're trying to do to me, I've been through this before. I want an attorney. I don't need anymore," Johnson says in the footage.

In a press release earlier this week, Greenfield's mayor said the city's investigation revealed "significant, highly concerning actions and patterns of behavior."

CBS 58 also obtained a call that Johnson allegedly made to 911 in which a man's voice is heard saying, "Hello, you f***ing pigs. Revenge is sweet."

Officials said their investigative report is more than 700 pages long.

Under state law, Johnson cannot be fired until after a formal hearing before the Police and Fire Commission and the commission determines it has jurisdiction over the charges.

Assistant Police Chief Eric Lindstrom is currently acting as chief.
