(CNN) -- A New Jersey police officer plead not guilty on Friday, a day after he was arrested and charged with setting fire to the house of an Edison police captain and his family. Michael A. Dotro was arrested on Thursday at his home in Manalapan, New Jersey, after an investigation by the Middlesex County prosecutor's office and the Monroe Township Police Department. That investigation determined that a fire at the police captain's home early on May 20 had been intentionally started outside the house. Police, EMT personnel and firefighters were called to the two-story, colonial-style home of police Capt. Mark Anderko shortly before 4 a.m. on May 20. Anderko was in the house with his wife, two children and 92-year old mother.
