London: The British police on Tuesday arrested two teenagers in connection with the unprovoked killing of 23-year-old-Indian student Anuj Bidve, who was shot dead on Monday in what could be a hate-crime.

Bidve was visiting Salford in Manchester over Christmas holidays with other Indian students on Monday morning.

One 16-year-old is being questioned by the Greater Manchester Police along with a 17-year-old. The identity of the two teenagers has not been revealed.

He was with nine other Indian students when he was accosted by two white men, one of whom shot him from point blank range after a "very short" conversation.

Hailing from Pune, Bidve was a postgraduate student of Microelectronics at Lancaster University and was visiting friends in Manchester during the Christmas holidays with other Indian students when he was gunned down.

Meanwhile, a post-mortem revealed that Bidve, a postgraduate student of Microelectronics at Lancaster University, died as a result of "gun trauma" to the head.

The police have not confirmed what was said during the short conversation between the killer and his victim.

Detectives are continuing to make house-to-house inquiries and are reviewing CCTV footage.

Tributes to Bidve have been paid by friends and family on Facebook, where pages have been set up to help bring his body back to India, and also appeal for peace marches in memory of Bidve.

The police is not ruling out racism as a motive for the killing after the two men who approached the group of students early on Monday morning were described as white men.
