Two builders surrendered and appeared in Bronx Supreme Court Wednesday to answer to perjury charges a month after NYC?s former top cop pleaded guilty to accepting gifts for his apartment.

Frank and Peter DiTommaso, the owners of Industrial Interstate Corp., pleaded not guilty to the charges. The New Jersey men, who reportedly have ties to the mob, are accused of lying to the grand jury probing renovations of Bernard Kerik?s Bronx apartment while he was the city?s correction commissioner. Kerik pleaded guilty in June to accepting $165,000 in gifts from Industrial Interstate Corp. He has to pay more than $200,000 in fines, but avoided jail time. Kerik has not said whether he helped the company get contract work.

The DiTommasos declined to comment to News 12 The Bronx. They are due back in court September 20 and face up to seven years in prison, if convicted.
