HAYWARD -- A convicted child molester was arrested on suspicion of assault with a deadly weapon Tuesday after he reportedly stabbed a man who police say denied him sex.

Cronthicite Allen Williams, 51, of Hayward, was taken into custody a few hours after the reported 7 a.m. attack took place at his home in the 25000 block of Tarman Avenue off Jackson Street, said Sgt. Ken Forkus.

The victim, a 29-year-old Hayward man, told police that he and Williams -- who the victim had known for about a year -- were at up all night smoking methamphetamine and that Williams asked him if he could have sex with him in exchange for using his meth pipe, Forkus said.

When the victim refused the sexual advance, Williams reportedly got angry, grabbed a pocket knife and slashed the victim's neck and left arm, according to police.

The victim suffered serious injuries and drove himself to St. Rose Hospital, where medical personnel notified police. He suffered a 4-inch cut that required 10 stitches to his neck and three separate 6-inch cuts to his arm that also required stitches.

He was treated and released later that day, Forkus said.

A few hours later, Williams was arrested at his home without incident on suspicion of assault with a deadly weapon.

Williams, who police say is a convicted sex offender stemming from a 1997 child molestation conviction in Alameda County, also has a domestic violence conviction.

As of Tuesday morning, he remained incarcerated at the Santa Rita Jail on $30,000 bail and was due in court to be arraigned on Thursday.
