Charles Ross was arrested this week for allegedly stealing steaks, lobster, salmon and boxes of shrimp off trucks making the rounds at high-end Manhattan restaurants.
A person who answered Ross' cellphone Friday told the New York Post Ross did quite well selling the hot items to other restaurant.
"A couple thousand (dollars) a week," the acquaintance estimated.
"He knows a lot about life and business and school and math," the friend said, adding the onetime teacher "just fell off."
Police told the Post Ross had reinvented himself as a career criminal with three separate stretches in prison for robbery dating back to 1975.
Ross was nabbed Monday while allegedly wheeling a handcart loaded with purloined treats on West 47th St. He was jailed on $20,000 bond, sources told the Post.
