Police said Officer Andrew Ricks attended the Vital Remains show at West End Trading Company while in uniform on Nov. 13.

Reports said Ricks joined the band on stage and sang a song called “Dechristianize,” which included the lyrics “Let the killing begin.”

The incident was caught on camera and a copy was sent to Police Chief Cecil Smith.

The video was also posted to YouTube.

Ricks’ authority to perform his law enforcement duties was removed.

Smith said in a report that, “An incident of this nature erodes the thin fibers of trust which already exist between the community and the police and it will not be tolerated within the Sanford Police Department."

Reports noted that Ricks had submitted a letter of resignation from the department on Oct. 30 with a pending separation date of Nov. 20.

The department was made aware of the incident on Nov. 17.
