Police say four people forcibly tattooed their roommate with racial slurs and obscene images while holding him hostage for three days in a Philadelphia basement.

The two men and two women, who range in age from 19 to 27, are charged with aggravated assault, reckless endangerment, kidnapping and related counts.

Police said the 52-year-old victim called 911 on Tuesday and told investigators he was held against his will in the basement of a home in the Mayfair neighborhood where he lived with the four suspects. The man said he was beaten and tattooed by three of them.

Police said the victim's lower arms were covered with nearly a dozen offensive tattoos. Investigators say his hands were badly bruised and swollen and his eyes, legs, ribs and torso were also bruised.
