"This afternoon, he was walking towards his hostel around 2.00 pm from the college when a speeding tractor hit him from behind," he said.
Saleem was seriously injured and rushed to a nearby hospital, where he died during treatment, the SHO said.
"We have informed the embassy in New Delhi and have arrested the driver of the tractor," Khan said.
