According to reports, neighbours found the family, including assistant Professor Alok Gupta, lying in a pool of blood. His wife Sonam, father Sudheer Gupta and brother Prashant were among the injured. In a police complaint, Sonam said, 'I was asleep in my room with the children. Around 3.30 a.m. on Tuesday, I heard a loud noise and I went outside. To my horror, I saw some men repeatedly stabbing my husband with long knives. I tried to save him and screamed for help. The men stabbed me too. Other members of the family arrived and the assailants tried to flee. We managed to catch one of them. At least 8-10 men entered our house by scaling the boundary wall." She further added, 'The attacker said his name was Shahbaz and he had been sent by notorious criminal Shageer Khan.' /IANS
