William S. Brookbank

EAU CLAIRE — A borough man is being held in the Butler County Prison without bail after he allegedly sexually assaulted a 5-year-old girl, and then threatened to kill the child's mother.

State police Wednesday arrested William S. Brookbank, 49, on felony charges of child endangerment and corruption of minors, and misdemeanor charges of indecent assault and indecent exposure.

Investigators on Tuesday interviewed the girl after her mother contacted police about the alleged abuse of her daughter at the defendant's mobile home in Eau Claire, according to court documents.

The youngster recounted that Brookbank pulled down his pants, exposing himself, and inappropriately touched her, police said.

A full report will appear in the Butler Eagle.
