An unregistered sex offender has been arrested for lewd and lascivious behavior at the downtown YMCA.

It happened at the YMCA, 402 N. Market, Wednesday night. The 39-year-old man exposed himself and did inappropriate things with children present, police said.

Adults who were supervising the children noticed the man fondling himself and reported the incident.

"This is certainly something we do not want going on in our community," Capt. Doug Nolte said.

The man was booked on lewd and lascivious behavior. Through the investigation, police found the man was a convicted sex offender. Jail records show he's currently being held on charges he violated his probation as a sex offender and a fugitive from justice warrant out of California.

Through police records, the man has been identified as Charles Miller. According to the Kansas public offender registry, Miller was convicted of molesting a 3-year-old child in California in 2005. As terms of his sentence, he was ordered to register as a sex offender for life.

The offender site says Miller last updated his information in May of this year.
