AGRA: Uttar Pradesh police constables will observe ‘black day’ on October 5 in a bid to protest against the arrest and suspension of constable Prashant Chaudhary, the main accused in the Apple employee Vivek Tiwari murder case.The cops also threatened to go on indefinite fast and strike if charges against the accused constable are not dropped.Messages and post about the black day are being widely shared among the police personnel on Facebook and WhatsApp “We have asked all constables of UP police to gather at Allahabad and observe October 5 as ‘Kala Diwas’ in order to protest against the senior officers of department, who instead of supporting their men, prefer to punish them,” general secretary of Police Non-gazetted Employees Welfare Association, Uttar Pradesh, Avinash Prakash Pathak told TOI.“On Friday, the cops will wear black ribbons to protest against the arrest and suspension of constable Prashant Chaudhary. The gathering will also be attended by the senior lawyers of Allahabad High Court who will give legal help to constable Chaudhary,” said Pathak, who is currently posted in 37 PAC in Kanpur.“Constable Chaudhary, of 2016 batch, was on his regular duty. He and his colleague who were on UP police motor-bike were attempted to be crushed under the wheels of car driven by deceased Vivek Tiwari. Therefore, Chaudhary’s act was of self-defense and not a criminal intent. The senior police officials without probing the matter took action against their man,” he added.On September 29, 38-year-old deceased Tiwari, a general area manager of tech giant Apple, was allegedly shot dead by Chaudhary in Gomti Nagar Sector-6 area of Lucknow.In support of the move, to observe October 5 as black day, a bunch of cops posted pictures of themselves on WhatsApp and Facebook by wearing black ribbons on their arms to express solidarity with accused constable Chaudhary.While in few posts on social media, policemen posted vicious comments and videos condemning his arrest and suspension.In one of the videos, constable Sarvesh Chaudhary of Etah police claimed, “Constable risk their lives on duty, but the officials instead of backing their men punish them in their hard times." Last year, Sarvesh in Facebook post complaint to PM Modi about alleged harassment by senior officers.One constable Vishnu Chahar of Agra police used derogatory and foul language against the wife of the deceased, but later deleted it.The call for protest comes at a time when the state's Director General Police OP Singh in a statement called the accused cop a "rogue in uniform" and said policemen like him must be served with strictest of punishment.Constable Brijendar Singh Yadav, national president of Non-gazetted Police Welfare Association UP, in his letter to CM Yogi Adityanath threatened to go on indefinite fast if the charges against the constable are not dropped.Responding to the matter, DGP office PRO Vivek Tripathi said, “Departmental action will be taken against men who are found provoking colleagues in the department.”
