A man and a teenager have been charged with forcibly tattooing an obscenity on the forehead of a 17-year-old boy, police said Monday.

Norwich Police Officer Craig Berry declined to describe the tattoo, except to say it was a phrase.

"It's just ludicrous that someone would do something like this to another person," Berry said.

Kenneth D. Peer, 23, of South New Berlin and a 17-year-old boy from Earlville were charged with felony assault and unlawful imprisonment. Police were withholding the name of the 17-year-old, who was charged as a youthful offender, Berry said.

The pair were being held in the Chenango County jail on $25,000 bail. They were to return to court on March 29.

The victim — whose name also was withheld by police — walked into the Norwich police station Friday to file a complaint against his attackers. The victim told officers he had been held down by a man and another teen at a Norwich residence while they forcibly tattooed the vulgarity.

Police have not established a motive for the attack, Berry said.

Berry said the attackers used a homemade tattooing instrument. Berry said it was likely the victim would require plastic surgery or a laser process to remove the ink.
