Chief Chris Moore said Wednesday he’s launching an internal investigation into who in his department leaked a photograph.

A short time later, an officer took a photo of the citation and it was posted on a social media website.

In a department memo, Moore issued a stern warning to officers that such conduct violates department policy.

Reed has been at odds with the San Jose Police Officers’ Association and other unions for a June ballot measure to pare city worker pensions. Voters overwhelmingly approved the measure and the officers’ union is suing to block its provisions.
