(CNN) -- A grand jury has indicted polygamous sect leader Warren Jeffs on a second sexual assault charge in connection with a probe of his Texas compound, prosecutors said Wednesday. The charge against Warren Jeffs stems from a probe into his sect's Yearning for Zion Ranch near Eldorado, Texas. The Schleicher County, Texas, grand jury charged Jeffs, who already could be sentenced to life in prison after being convicted of a different charge in Utah, with a first-degree felony count of aggravated sexual assault. The indictment is Jeffs' second in Schleicher County. In July, he was charged with sexually assaulting a child under 17.
