The Batala police was playing into the hands of state government and keeping the activists of the Indian Federation of Trade Union (IFTU) into illegal confinement, said state convener of IFTU Harbhawan Singh.
He said the Civil Lines police raided the residences of various office-bearers of IFTU and took into custody five of its office-bearers, including state president Gurmeet Singh Bakhtapur.
"The SHO of the Civil Lines police station, KP Singh, raided their residences, misbehaved with the women present in the houses and forcibly took the office-bearers to the police station, where they were kept in illegal custody," he added.
It was only after the activists of IFTU threatened to hold a dharna against the police, the SHO released four of the activists, but did not release Bakhtapur.
The union leader said if the police did not release Bakhtapur, they would move the court to seek the release of their leader and would also organise a dharan against the police.
Batala SSP Tulsi Ram said the police had taken Bakhtapur into custody as a preventive measure and he would be presented before the magistrate on Thursday.
