A man accused of torturing a Quincy dog is being held on $500,000 bail for allegedly stealing $130,000 from the elderly woman for whom he was a caretaker. At his arraignment Tuesday in Norfolk Superior Court in Dedham, Radoslaw Czerkawski, a 32-year-old Polish immigrant, pleaded not guilty through an interpreter to two counts of larceny of property over $250, one count of larceny of property over $250 from a person over the age of 60, and one count of attempted larceny. While Czerkawski was already being held without bail on 12 animal-cruelty charges and a count of misleading a police investigation for his alleged involvement in the torture of a Quincy dog, the judge imposed the additional bail without prejudice. The bail amount will be discussed during a pretrial conference on all the charges on March. 5.
