ELIZABETH, N.J. (AP) _ A homeless, hatchet-wielding hitchhiker who became an Internet hero earlier this year was arrested Thursday for allegedly beating a New Jersey lawyer to death inside his home, authorities said.

Caleb ``Kai'' McGillvary, who became known as ``Kai the Hatchet Wielding Hitchhiker'' after intervening in an attack on a California utility worker, was arrested on a murder warrant at a Philadelphia bus station, according to Union County Prosecutor Theodore Romankow. He was being held on $3 million bail.

Earlier in the day, Romankow said McGillvary was wanted in the killing of Joseph Galfy Jr., a Clark, N.J. attorney found dead in his home on Monday.

Galfy's body was found two days after authorities said he met McGillvary in New York City. He was found wearing only his underwear and socks by police who went to his home to check on his well-being.
