The incident occurred yesterday when a cleanliness drive was being conducted under school principal Awadhesh Kumar.
"While cleaning, Kumar and his staff spotted a locker stack in teachers' room, which was lying unused and gathering dust. Kumar asked his staff to open each locker to clean them. Out of 20-odd lockers, staff could not find keys of five lockers," said Chandkheda police inspector K K Desai.
Kumar then ordered his staff to break these lockers open and found one bag each from two lockers, he said.
According to police, these lockers have been given randomly to teachers and to other staff members to store their belongings. However, there was no record available about who possessed which locker.
"Kumar claims that he joined as principal two years back and these lockers were never used during his tenure. We have questioned many staff members and teachers, but we are still unable to trace the person who put those bags into these lockers," Desai said, adding that he has informed the Income Tax department to probe any tax-related angle.
