Agitators broke in and vandalised hundreds of factories and corporate offices in and around Noida on the first day of the two-day trade union strike on Wednesday.
Dozens of persons including police personnel sustained injuries during clashes between the protesters and the public.
Police have arrested 32 persons for damaging private and public property in Noida.
No incidents of violence was reported from any other part of Uttar Pradesh.
The strike was successful as banks and PSUs remained shut and public transport was paralysed. In the state, trade union strikes were peaceful in the past. But on Wednesday, entrepreneurs and the corporate offices were taken aback by the vandalism.
The situation was the worst in Sectors 57,58, and 63 of Noida, where dozens of factories and offices were ransacked by the protesters, who set many cars on fire and destroyed police and government vehicles.
It has been alleged that police and the district administration didn’t take any preventive measures. Police made no elaborate security arrangements to protect the businesses in Noida, the most industrialised spot on the state map.
Police are also accused of largely remaining passive and intervening only when the situation went out of control.
The Noida Entrepreneurs Association described the Wednesday’s incidents as the blackest chapter in Noida’s history and threatened to shift the industrial bases if the UP Government failed to provide security to the industries.
