Surendra Singh, MLA from Bairia constituency in Ballia, said he decided to call off the protest, after he got a phone call from Deputy Chief Minister Maurya late last night.
He said, "Yesterday when a person was bringing a tractor full of sand here, he was stopped by one Sub-Inspector Virendra Yadav, who demanded Rs 2,000 from the person."
But when he refused to give him the money, the sub- inspector beat him up, snatched Rs 500 and mobile phone from him, Singh alleged.
Meanwhile, Superintendent of Police Sujata Singh today ordered a probe into the incident. "If the need arises to register a case after the probe is complete, it will be done," she said.
