Colorado Springs police are searching for additional child victims of sexual assault after an investigation revealed a local racquetball coach allegedly engaged in sexual contact with two juveniles.

On Sept. 3, the Colorado Springs Police Department initiated an investigation into a report of sexual assault on a child involving 65-year-old Mark Sikorski. Investigators say Sikorski engaged in sexual contact with two underage juveniles, which resulted in his arrest on Sept. 9.

Continued investigation by detectives with the Crimes Against Children Unit revealed Sikorski had been a racquetball coach for juveniles in Colorado Springs. Detectives now believe there may be other victims and unreported cases of sexual assault by Sikorski.

If anyone, or anyone known to you, has been a victim of Sikorski, contact police at 719-444-7000 or the Pikes Peak Area Crimes Stoppers at 719-634-STOP (7867).

Police say they are not releasing a photo of Sikorski to the public to preserve the integrity of the investigation, the department stated Wednesday.
