COLORADO CITY , Arizona ( CNN ) -- A 16-year-old girl in Arizona has alleged sexual abuse in a Fundamentalist Church of Jesus Christ of Latter-Day Saints community , sources in Arizona told CNN Friday . Warren Jeffs is the jailed leader of FLDS groups in Arizona , Utah , Texas and elsewhere . Authorities are investigating calls made by a teenage girl alleging abuse in her home by a male relative , according to the sources , who said the calls were similar to those made last week to Texas authorities from the polygamist sect 's ranch in Eldorado , Texas . The Texas calls prompted a law enforcement raid in which more than 400 children were taken into state custody . The sources told CNN the Arizona calls came from a teenager in an FLDS household . Church members openly practice polygamy in Colorado City and in Hildale , Utah -- two towns straddling the Arizona-Utah state line . Warren Jeffs , the 52-year-old leader and `` prophet '' of the 10,000-member sect , was convicted in Utah last year on two counts of being an accomplice to rape , charges related to a marriage he performed in 2001 . He faces trial in Arizona on eight charges of sexual conduct with a minor , incest and conspiracy . Critics of the sect say it forces girls as young as 13 into arranged marriages .
