Four men attacked a man with a knife and shot at in a chock-a-block bylane of northeast Delhi's Shastri Park last evening, the police said. The accused have been charged with attempt to murder, they said. CCTV footage from the area showed the crammed bylane suddenly descending into complete chaos, with locals running away. Within seconds, the bustling lane was empty but for the four accused - Bilal, Saud, Firoj, and Salim - running behind the victim, 25-year-old Sameer Ahmed, and stabbing him with a knife.
