PARMA, Ohio -- Parma police are looking for children who may have been victims of a man officers arrested on rape charges.

Parma investigators said they think Richard Geiger may have been involved with more than one child. Officers took the 63-year-old into custody earlier this week.

A 14-year-old boy told his mother that Geiger assaulted him at his Broadview Road apartment. Police said Geiger picked the boy up, showed him pornography and then attacked him sexually.

The suspect was charged with one count of rape.

This isn't the first time Geiger has been investigated. Police said he served time for gross sexual imposition after an arrest in 1981.

If you have any information that could help investigators, they're urging you to call the Parma Police Department.
