An Internet celebrity known as "Kai the Hatchet Wielding Hitchhiker" has been arrested by police as a suspect in the killing of an elderly Clark, N.J. man.

The Union County, N.J., Prosecutor's Office said Philadelphia police arrested Caleb Lawrence McGillvary, 24, at a bus terminal Thursday in Philadelphia, reports.

McGillvary is the main suspect in the weekend killing of lawyer Joseph Galfy, Jr. 

Union County Prosecutor Ted Romankow said McGillvary met Galfy in Times Square in New York City Saturday night and went home with him, reports. Galfy was later found dead Monday inside his home as a result of blunt force trauma.

McGillvary is homeless but considers himself "homefree." McGillvary is also known as Kai Lawrence, Caleb Kai Lawrence and Kai Nicodemus.

McGillvary rose to fame after saving a woman by fighting off a 300 pound man with a hatchet and giving a local TV reporter in Fresno, Cal. an animated recounting of the incident.

Authorities reportedly believe that McGillvary relies on the generosity of strangers for food, lodging and transportation.

Prior to his arrest, authorities knew that McGillvary cut his hair in an attempt to alter his appearance.
