Charlie Sheen has released a video of himself speaking an open message to the ex-police officer who is thought to be responsible for the shooting of three police officers, TMZ reports.

Ex-cop Christopher Dorner is now a fugitive. Having been fired from his job as a police officer in 2008, he has since accused LAPD, where he used to work, of racism. In an online 'manifesto', in which he threatens the safety of LAPD personnel and their families, he spoke of Randy Quan, who was a part of the 'review process' which led to Dorner's dismissal. Last Sunday (3rd February), Quan's daughter and her fiancee were found dead. 

The LA Times quotes Dorner's manifesto, a passage that relates directly to Quan: "Your lack of ethics and conspiring to wrong a just individual are over. Suppressing the truth will leave to deadly consequences for you and your family. There will be an element of surprise where you work, live, eat, and sleep," he wrote."I never had the opportunity to have a family of my own, I'm terminating yours."

He also wrote about Charlie Sheen, describing him as "effin' awesome," a comment which has spurred the actor into action. In his video, Sheen says:  "You mentioned me in your manifesto, so thank you for your kind words. I am urging you to call me. Let's figure out together how to end this thing."
