A registered sexual predator who was recently released from prison was arrested after talking to children at an Oakland Park community center last week.

The Broward Sheriff’s Office said that Frederick Muller, 38, was seen at the Collins Community Center “trying to lure children to him” to talk to them on Sept. 8. It’s believed the children had just been let out of school from Oakland Park Elementary School.

A witness who was uneasy about the interaction called the police, and Muller was located and arrested on three charges: failure to comply with registration law, failure to register as a sexual predator, and failure to renew information on his driver’s license. He remains at BSO’s main jail on a $10,500 bond.

He was previously released from prison on June 27, BSO said.

Law enforcement is asking the public to come forward if they believe one of their children had interacted with Muller that day. So far, they have not been able to get in touch with any potential victims.

According to the Broward County Circuit Court, Muller was arrested in 2006 in Coral Springs for lewd and lascivious battery on a child 12 to 15 years old; he was continually rearrested through 2014 for violating his probation. In 2015, there was an order vacating his status as a sexual predator.

Anyone with information about Muller’s interaction with the children at the community center is encouraged to call Det. Marlene Schnakenberg at 954-321-4789, or submit a tip through the SaferWatch app. To remain anonymous, contact Broward Crime Stoppers at 954-493-TIPS (8477), browardcrimestoppers.org or by calling **TIPS (8477).
