DENVER -- A 23-year-old man was charged Wednesday with fondling two young girls last weekend at Six Flag Elitch Gardens.

Ismael Armendariz faces two felony counts in connection with the May 21 incident.

According to the Denver District Attorney's Office, Armendariz is suspected of sexually assaulting two girls, ages 11 and 12, in a swimming pool at the amusement park.

He was arrested a short time later in a restroom of the park by two off-duty Denver police officers who were working there.

Armendariz was charged with two counts of sexual assault on a child and his bond was set at $10,000.

Six Flags recently added wording on the back of season passes to all 30 of its U.S. amusement parks, including Denver.

The wording states that Six Flags reserves the right to refuse entry to anyone convicted of a sex crime.

The amusement park said it does not actually plan to run background checks on everyone entering the park, but visitors seen acting inappropriately could be subjected to a check and thrown out.
