HAZARD, Ky. (AP) -- Police in eastern Kentucky have arrested four men charged with sexually abusing a 16-year-old boy.

Hazard police Capt. James East says officers arrested Brett Combs, Jared Fields, Phillip Riddle and Ora Walker on Thursday night. East says police became involved when they were contacted by the boy's school.

The Associated Press does not identify victims of sexual abuse.

East says the men, ages 18 to 21, forced the boy at knifepoint to perform sexual acts. The men also face charges of sodomy, unlawful transaction with a minor and kidnapping for holding the boy against his will. East says the attacks occurred on "more than one occasion" between January and mid-March.

They are jailed and will be arraigned Monday.

District Clerk Roger Collins did not have information on the men's attorneys.
