Refusing to pay toll, a bus driver tried to crush a toll plaza manager when asked to stop. This happened around 11.20 am on Sunday when a bus reached the Kherki Daula toll plaza and the toll collector asked the driver to pay the toll of Rs 60, but he refused and tried to flee, police said. On seeing that driver was trying to flee without paying, the manager signalled the driver to stop but he tried to crush him under the wheels.
