Protesters in India have fought running battles with police for a second day, as politicians battled in Parliament over who was to blame for the unrest.
Both sides have accused each other of starting the fighting
The clashes flared on Monday as workers from Honda Motorcycle and Scooter India protested at the firing of colleagues.
Many people were injured during the fighting and taken to hospital in the New Delhi suburb of Gurgaon.
Trouble erupted outside of the hospital again on Tuesday amid reports that the injured people were not being treated.
According to the BBC's Nagendar Sharma in Delhi, workers manhandled the deputy commissioner of Gurgaon before a large crowd gathered at the hospital.
As angry relatives raised slogans against the government, police officers ordered a cane charge to disperse the crowd.
The battles have escalated quickly
Water canons were also used to break up the protests, and hundreds of policemen were deployed across the city.
Some of the protesters said they were looking for relatives who were still missing after Monday.
"I want to see my brother," said one man called Veermati. "I saw him on TV yesterday, he was one of the leaders. We don't know what happened to him after that.
"I am furious. Nobody's telling me where my brother is."
His anger was reflected in the mood of many politicians, and in Delhi the Congress Party-led government came under a heavy attack.
Members of the opposition National Democratic Alliance walked out of parliament in protest, while others called for the state government to be dismissed and disciplinary action taken against the police.
Estimates about the number of injured have varied wildly
"Even animals are not treated like this," said Devendra Prasad Yadav, leader of ruling coalition member Rashtriya Janata Dal group.
India's National Human Rights Commission demanded that detectives from the Central Bureau of Investigation probe the incident.
Bhupinder Singh Hooda, head of Haryana, the state where Gurgaon is located, said he was ordering a judicial inquiry into Monday's violent clashes.
Prime Minister Manmohan Singh had earlier expressed "anguish" over the clashes.
'Violence from both sides'
Police have been deployed across the city to control the violence
Monday's protest was called after four workers at the Honda plant in Gurgaon, near New Delhi, were fired and 15 others were temporarily suspended on charges of insubordination a month ago.
Workers have been demanding the reinstatement of the sacked workers and an increase in wages.
According to local television estimates, as many as 700 workers may have been injured in the violence on Monday.
Authorities said that the figure was closer to 100, with about half of those people needing hospital treatment.
"There was violence from both sides," said Mr Hooda.
Honda's plant employs some 1,900 staff, the majority of whom have been working a go-slow since May.
The company has estimated that the industrial action has cost it about 2.5bn rupees (£33m; $57m).
