LAS CRUCES, N.M. -- A New Mexico man who investigators say set his prosthetic leg on fire with a pocketed crack pipe has been arrested.

Deputies say they found 47-year-old Randy Malone naked along U.S. 70 with his prosthetic right leg in flames on July 5. He was treated for burns to his leg, back and buttocks.

A witness later told authorities he agreed to give Malone a ride into Las Cruces, but dropped him off after the passenger lit a crack pipe inside the vehicle.

Dona Ana County deputies arrested Malone on Sunday at his home after the man's brothers tipped investigators. Malone was being sought on a warrant for making a false report.
