PHOENIX -- A man charged with sexually abusing a girl for six years is a correctional officer at the Federal Correctional Institution, Phoenix police confirmed Thursday night.

Loren Williamson, 33, was booked into the Fourth Avenue Jail on four counts of sexual conduct with a minor and three counts of child molestation.

Police said the abuse started when the victim was 6 years old and continued until authorities recently got a tip.

The Phoenix Police Department's Special Assignments Unit arrested Williamson around 4:30 a.m. Wednesday near 17th Street and Union Hills Drive.

Officers said Williamson was involved with the Wiccan religion and may have used its mystical traditions as a way to spark the interest of young girls.

The Wiccan religion, also known as "the craft," or "wicca," is part of contemporary paganism.

Rituals usually include meditation, music and the use of magical tools.

Officers said they are not immediately aware of any other victims, but it appears that there could be more who have not yet come forward.

People with information related to the caseshould contact the department's Crimes Against Children Unit at 602-534-3200 or Silent Witness at 480-WITNESS.

Williamson is being held without bond.

The institution where Williamson works, located 25 miles north of downtown Phoenix, is a medium security facility for male offenders. An adjacent satellite prison camp houses minimum security female offenders.
