A routine bank audit has exposed an alleged corporate fraud of over Rs 80 lakh, leading Shivaji Nagar police to book a company director and a production supervisor for cheating, criminal breach of trust and common intention.

According to police, the FIR was registered on Tuesday based on a complaint by Lakshminarayan Srinivasan, 65, director of an Ambernath MIDC-based company that manufactures industrial water-filtration equipment.
