Prescott police arrested a convicted sex offender Wednesday on charges of furnishing illicit materials to minors at Willow Lake Park.

Police said in a Thursday press release that they arrested 48-year-old Albert E. Nash Jr. after a parent checked a park restroom prior to letting their kids use it and found pornographic material and a note soliciting sex in open view.

The restroom was near a playground area, the press release said.

An investigation led police and Yavapai County Adult Probation officers to Nash, police said.

Police booked Nash into the Yavapai County Jail where they are detaining him without bond, the release said.

Nash is a convicted and registered sex offender and previously had served 11 years of a 20-year sentence in prison for two counts of sexual abuse, police said.
