Tensions ran high in parts of Noida as industrial workers continued protests over wages, with the agitation turning violent in some areas.
The situation worsened in Phase-2 and sectors 60 and 62 of Noida, where protesting workers clashed with police.
Vehicles were set on fire and stones were hurled after a female worker was allegedly hit during police action.
Workers have been demonstrating for the past four to five days, demanding a wage revision that they say is long overdue and should be in line with labour laws.
The protests in Noida have escalated after the Haryana government announced a 35% increase in minimum wages across all categories of workers.
Under the revised structure, minimum wage for unskilled workers was raised from ₹11,274 to ₹15,220 per month, while semi-skilled workers saw an increase from ₹12,430.18 to ₹16,780.74.
Skilled and highly skilled workers also received a 35% hike.
Delhi police has been put on high alert amid the protests, with several teams deployed at all commutable roads connecting Noida to different parts of Delhi.
