The prime accused in the horrific murder of a Dalit law student in Allahabad was arrested on Wednesday from Sultanpur in Uttar Pradesh, police said.

Vijay Shankar was taken into custody from the house of Chandra Bhadra Singh, a political activist.

After a scuffle over a trivial issue at an eatery last week, Dileep Saroj was brutally assaulted by four men led by Singh. The 26-year-old LLB student had gone into a coma and later died.

The killing had been filmed by a passerby and the clip went viral, leading to outrage. His autopsy showed 30 injuries on his body, including several fractures.

Students of Allahabad university went on a rampage after Saroj's death. The Uttar Pradesh government, after facing much flak, announced a compensation of Rs 20 lakh to the family of the student.
