Suzuki Motor Co.'s Indian subsidiary resumed operations Tuesday at its violence-wracked plant in Manesar in the northern Indian state of Haryana after a one-month hiatus.

Maruti Suzuki India Ltd., India's largest automaker, shut down the plant July 21, three days after worker violence led to the death of a plant manager and injured more than 100 people, including two Japanese workers.

To ensure the safety of employees, the local government is expected to post more than 500 security troops in and around the factory, while Suzuki has also stepped up security.
