FORT WORTH, Texas —  A father sodomized his 18-year-old stepson to avenge the teenager's alleged rape of the man's 8-year-old daughter, police said.

The father, 32, turned himself into to authorities on Friday and was released from jail Saturday after posting a $17,500 bond. He faces a charge of aggravated sexual assault.

The stepson was arrested Jan. 2 and charged with suspicion of aggravated sexual assault. Police say the father caught him assaulting his daughter, and a subsequent examination at a hospital revealed the girl had been sodomized.

Sgt. Cheryl Johnson, supervisor of the Fort Worth sex crimes unit, said in a story posted Saturday on the Fort Worth Star-Telegram's Web site that people need to "allow the criminal justice system to work for them."

"This is a very unique case, but we have a criminal justice system in place, and no one can take the law into their own hands," Johnson said.

The Star-Telegram didn't identify the father or the stepson to protect the identity of the girl. Fort Worth police didn't immediately return phone and e-mail messages from The Associated Press.
