Sacramento Police investigating sexual assault claim involving Assemblyman Devon Mathis

Sacramento Police have launched an investigation into a possible sexual assault after receiving allegations against Assemblyman Devon Mathis.

Investigators say the claims came from a third party and officers are trying to determine whether a victim or victims exist.

The investigation began after Joseph Turner, founder and executive director for American Children First, posted a blog Thursday on the nonprofit's website targeting Mathis and raising sexual assault allegations.

Because of the nature of circumstances police are not able to comment on further details.
