Calcutta, Sept. 16 :    Calcutta, Sept. 16:  Sajal Barui, who hit the headlines eight years ago for brutally killing three members of his family, has managed to elude the police even 24 hours after his escape from Calcutta National Medical College and Hospital on Sunday. Twentyfour-year-old Sajal, serving a life sentence in Midnapore jail, escaped from the hospital's urology ward early on Saturday. He was admitted to the hospital on August 28 for suspected renal failure. He managed to hoodwink two reserve force constables and a large police contingent gathered on the hospital premises to carry out eviction of slum-dwellers. Police have suspended the two reserve force constables, Joydeb Barui and Gautam Sarkar, for 'possibly aiding Barui in his escape from custody'. Deputy commissioner of police (headquarters) Banibrata Basu said: 'Efforts are on to find out if the constables aided Barui in his escape.' The constables maintain they were 'half-asleep' and noticed Barui's disappearance 'later'. A senior police official said: 'The involvement of certain sections of the hospital staff in Barui's daring escape cannot be ruled out, as he seems to have evoked a lot of sympathy.' Deputy commissioner of police (eastern suburban division) Sanjay Mukherjee said: 'We are working on several leads. The details cannot be divulged right now, but we will definitely bring back Barui to justice.' Police believe Sajal might have feigned illness and overstayed at the hospital in order to escape. In November 1993, Sajal, along with four friends, had throttled and hacked to death his father, stepmother and brother at their Mall Road apartment in Dum Dum.
