The main accused in the killing of a Dalit student of Allahabad University was arrested today, police said.

Vijay Shankar Singh, a travelling ticket examiner, was arrested from the Sultanpur bus stand around 7 am, Senior Superintendent of Police Akaash Kulhari said.

Dileep (26), a second year LLB student, was thrashed by a group on Friday following an altercation outside a restaurant. He succumbed to injuries two days later.

Kulhari said police have recovered the iron rod and the brick used in the crime.

Four people have already been arrested in connection with the incident.

The Yogi Adityanath government came in for criticism from rival parties over the killing, with Samajwadi Party chief Akhilesh Yadav saying it showed Uttar Pradesh was in the "grip of criminal elements".

Bahujan Samaj Party supremo Mayawati said the killing was a result of "narrow and casteist politics of hatred" being pursued by the ruling BJP.

Protesting the death of Dileep, Allahabad University students had torched a state-run bus on Monday.
