Three men pleaded not guilty in the Sungai Petani Sessions Court today to committing mischief by fire at a factory here in April.

Lorry attendant, M Kathiresan, 31, salesman P Selvanathan, 28, and contract worker Lim Chee Kwang, 35, made the plea after the charge was read out to them by the court interpreter before judge N Priscilla Hemamalini.
