Four union leaders have been booked under the National Security Act for misbehaving with the Labour Commissioner and engaging in violence at the office of the Labour Department in Kanpur, officials said on Saturday.
Superintendent of Police (Crime) O P Singh told reporters that the National Security Act (NSA) has been invoked against the four leaders - Chandrashekhar, President of LML labour union, Shyamji Yadav, Pooran Rajput and Rajkumar of the JK Jute Mill labour union.
On July 15, employees of LML company and labourers of JK jute mill staged a dharna outside the office of Labour Commissioner. They wanted the commissioner to listen to their demands.
When the Labour Commissioner Sitaram Meena came out of the office to go elsewhere in his car, some protesters misbehaved with him. This infuriated the Labour Commissioner office staff who retaliated and the ensuing clashes resulted in damage to property and vehicles of the office, police said.
Taking action against the protesters, police and district authorities detained several of them and charged 15 persons under the Criminal Act and attempt to homicide.
SP (Crime) said that the four persons against whom the NSA has been invoked have been in jail since July.
