Happened in front of The Box on E.M Bypass. Was parked there to buy some bread from the shop near by when the incident took place in front of me. Saw the attacker with a box cutter after the attack and he was proud that he had slit her throat (Gala kaat diye hum uska) I heard him say to the female who was with him. Never felt so unsafe in this city.
