The Uttar Pradesh police arrested Bharatiya Janata Yuva Morcha leader Shikhar Agarwal, accused of instigating violence in Bulandshahr, late Wednesday evening.
Sources in the police here said that Shikhar, also one of the accused in the killing of police inspector Subodh Kumar Singh, the station house officer of Siyana police station, was arrested from Hapur.
Shikhar Agarwal was interrogated by police before being produced in a local court, which sent him to 14-day judicial custody, they added.
On December 3 last year, violence had erupted in Siyana tehsil of Bulandshahr after cattle carcasses were found strewn in the fields outside Mahaw village, resulting in the murder of Subodh Singh and a youth named Sumit Kumar.
According to police, Shikhar Agarwal was involved in instigating the mob which went on the rampage on December 3, and killed the police officer and set a police outpost and a number of vehicles on fire.
The police took more than a month to arrest Shikhar Agarwal though he kept on uploading his videos on social media claiming his innocence in the whole incident. He also gave interviews to several TV channels while in hiding.
Around six months back, Shikhar Agarwal was appointed head of the newly-formed Siyana unit of BJYM, a police official said.
Siyana police station had registered an FIR against 27 named people and 50-60 unidentified persons in connection with violence.
Local Bajrang Dal leader Yogesh Raj, also a main suspect in the case, was arrested by the police on January 3.
The police said that over 35 people had been arrested so far in connection with the case, including Army jawan Jitendra Malik, Prashant Nat who allegedly shot the inspector dead and Kalua who had attacked him with an axe.
