Amid a political furore over killing of a police inspector and a man in Bulandshahr in a case of mob violence, Uttar Pradesh chief minister Yogi Adityanath on Tuesday night ordered a thorough probe and directions were issued for strict action against those involved in the alleged cow slaughter, said to be the trigger for the brutal incident, a senior official said.

A day after the tragic incident, Adityanath held a meeting in Lucknow with chief secretary, DGP, principal secretary (home) and additional director general of police (intelligence).

After the chief minister’s meeting, Additional Chief Secretary (Information) Avinish Awasthi said, “The UP Chief Minister directed (officials) for a thorough probe in the incident. Instructions were also issued to take stringent action against people involved in cow slaughter.”

“The incident is part of a bigger conspiracy, and hence all those directly or indirectly related to cow slaughter should be arrested in a time-bound manner,” he said.

Meanwhile, four people were arrested in connection with the killing of Inspector Subodh Kumar Singh and a young man in Bulandshahr violence after alleged cow vigilantes went on a rampage, police said on Tuesday.

The police, however, maintained it would be too early to conclude about the involvement of any organisation in the violence although local officials linked the mayhem to rightwing Hindu groups.

The police said the main conspirator behind Monday’s mob violence was Yogesh Raj, who is on the run and is said to be a Bajrang Dal activist.

Additional Director General (Law and Order) Anand Kumar said those arrested were Chaman, Devendra, Ashish Chouhan and Satish, who have been named in the FIR, while the prime suspect was Yogesh Raj.

“Those arrested have been found to be leading the crowd after being identified in a video. About 40-50 others who are unidentified were involved in the incident and police is confident of identifying them with the video evidence,” he said.

The official parried questions about the political links of the three key accused who are also said to include an activist each from the BJP and the Vishwa Hindu Parishad.

“Yes, Yogesh Raj is the main conspirator,” he said, adding that he was yet to be arrested.

He said six teams have been formed to probe the incident and an SIT has been constituted to investigate the matter.

On allegations that policemen fled the spot leaving the slain Inspector alone, Kumar said the circumstances in which police personnel left the place would be analysed and till then no action would be taken against anyone.
