Indian police are looking for almost 3,000 workers involved in rioting on Thursday that left one dead and 50 wounded, Asahi Shimbun reports.

The deadly riot erupted in the Maruti Suzuki, a car factory in Manesar, after a confrontation between the management and Maruti Suzuki Workers Union (MSWU) over the disciplinary case of one employee. Both sides claimed, in contradicting reports, that the other attacked first. The union accused the car manufacturer of anti-worker and anti-union activities. Workers attacked the factory using iron rods and other sharp tools, while other parts of the plant were set on fire. Twelve-hundred police officers secured the site and arrested 88 people facing murder, attempted murder and arson charges, commissioner of police, K.K. Sindhu, told Asahi Shimbun.

Maruti Suzuki is India’s biggest car manufacturer, with an annual output of 550,000 vehicles. The riot cost the company more than $500 million in lost production. Shares fell as much as 9.4% from 11%.
