Ayuba Wabba, national chairman of the Nigeria Labour Congress (NLC), on Tuesday led workers to protest the contemplated mass sack of its members by the Kaduna State government.
While the workers in railway, aviation, medical and other sectors complied by downing tools, others took to the street to demonstrate.
The state governor, Nasir El-rufai, had earlier declared Mr Wabba and his cohorts wanted for alleged economic sabotage and attacks on public infrastructure.
Mr El-rufai also promised to reward whoever will provide information on the whereabouts of the labour leader.
But hours after that declaration, Mr Wabba surfaced at the government house, protesting with members of the NLC. Moments later, alleged state-sponsored armed thugs appeared and disrupted the protest.
The workers had converged at the popular NEPA roundabout in the Kaduna capital city to continue the day two of their protest when the thugs invaded the area and started throwing stones and other dangerous weapons at them.
The attack forced many of the protesters to initially scamper for safety but returned after with the NLC boss accusing the state governor of being behind the attack.
He also dared the governor to come and arrest him.
“Let him come and arrest me. We are here and waiting for them,” Wabba said.
