The girl, a third year B.Tech student, had withdrawn Rs 50,000 cash from an ATM booth. She gave Rs 10,000 to a friend and kept the remaining amount in her bag, police said.
The two girls were walking towards Kaushalaya hostel in Knowledge Park when the bike-borne youth came and tried to snatch the victim's bag near Gurdwara Road, they said.
When the girl resisted, one of them shot at her and she suffered a bullet injury in her leg. They fled from the spot with the bag which contained Rs 40,000.
A case has been registered and a search launched for the accused, they added.
