India's leading carmaker Maruti Suzuki will restart production at its Manesar plant August 21, almost a month after the plant was shut down following violence by workers, Reuters reported.

The production at Maruti's largest plant in India was stopped July 18, after a manager was killed and scores injured when a section of the workers set fire to a part of the plant.

The production halt at the plant has cost millions of dollars and affected the sales as the stocks of Maruti's two most popular car brands - Swift and DZire - have dried out. The Manesar plant accounts for one-third of Maruti's car production capacity in the country and is the only plant that makes Swift, which is the most popular car in its segment.

Around 90 workers were arrested for rioting, arson and related crimes and more than 2,000 workers are still absconding, fearing arrest. The workers union has blamed the management for its anti-worker and inhuman treatment while the management has accused external forces and the union for triggering the riot.
