Two students of a government-run medical college were arrested on Tuesday for allegedly beating 16 puppies to death. The incident created large-scale outrage in the city after a video of it became viral on social media.

"Initially we zeroed in on five students who were identified on basis of inputs provided by students who shot the video. Two among them were arrested on Tuesday," a senior Kolkata Police official said. 

He also said that during interrogation the two had admitted the crime. Police are also probing whether any staff of the hospital were involved in the gruesome act.

The NRS Hospital authorities have already set up a probing committee to investigate the matter and has made it clear that stern action will be taken against those who are involved in the matter. The probing committee will submit its report to the hospital superintendent on Wednesday. 

During the day a section of animal rights activists who were protesting outside Kolkata's Entally police station allegedly vandalised the vehicle of a Deputy Commissioner.

"Thinking that the two accused were inside the Deputy Commissioner's vehicle a section of animal lovers tried to stop and vandalise it," a police official said.
