"Our attention has been drawn to complaints by the Public regarding hiking of fare by some transport operators. We have sent our teams to work closely with the police and identify operators involved in this violation for our immediate action," Meja noted.
He further appealed to all road users to be responsible, to avoid unnecessary crashes.
