The gory incident occurred in the state capital Bhubaneswar Sep 24, but came to light only after the critically injured woman's brother lodged a police complaint.

Later, Panda attempted to stitch her wounds, but when things got worse, he took her to a private hospital and fled after getting her admitted.
Panda has been arrested, a police officer told IANS.
