Authorities say a group of young men and teenagers sodomized a 15-year-old boy, critically injuring him in an attack that was recorded on video and shared among cellphones.

Christian County sheriff's Capt. Chris Miller said Thursday that the assault occurred at a home in Hopkinsville in western Kentucky. Authorities say three men and two juveniles have been taken into custody.

The victim was in intensive care Thursday at a hospital. Miller says the boy's condition has improved since the attack early Sunday left him with life-threatening injuries.

Police have not released a possible motive or many details about what happened. Miller says four people are accused of sodomy and another person had a video of the attack. The victim knew his attackers, and all are from the Hopkinsville area.
