Ghaziabad, March 4 -- The second suspect in last week's stabbing of YouTuber Saleem Wastik in Ghaziabad was killed in an exchange of fire with police late Tuesday, officials said. The development comes two days after his younger brother, identified earlier as the first accused in the case, was also killed in a similar encounter. Wastik was allegedly attacked around on February 27 at his office-cum-residence in Ali Garden, Loni. Two men, who were unidentified at the time, allegedly stabbed him and fled on a motorcycle. He remains critical at a Delhi hospital, according to his son, Usman Ahmad. Police said the first suspect, Zeeshan Ali, was tracked down on Sunday. He was allegedly riding a motorcycle with another man, later identified as Gulfam. Officers said the duo opened fire when a police team attempted to stop them. Zeeshan was killed in retaliatory firing, while Gulfam escaped. Both were residents of Khoda in Ghaziabad. On Tuesday, police said Gulfam was located beneath the Hindon elevated road near Khoda following specific inputs. According to Piyush Kumar Singh, additional deputy commissioner of police (crime), he was again riding a KTM motorcycle with an unidentified associate when officers intercepted him. "The team asked them to stop, but they opened fire. Police retaliated. The suspect sustained bullet injuries and was taken to hospital," Singh said. The second rider fled. Gulfam died during treatment at a private hospital in Indirapuram, said Nimish Patil, DCP (Trans-Hindon zone)....
