The woman, doing her fourth year engineering in a private college, was injured in the neck and shoulder and admitted to government hospital, where her condition was stated to be out of danger, police said.
The man was overpowered by the passersby and handed over to police who arrested him and filed an attempt to murder case.
She was in love with the man, one year senior to her, and they got married last March without the consent of her parents.
Irked by her refusal to withdraw the divorce plea, the man attacked her when she was waiting to board a bus in the busy municipal terminal in broad day light.
