During head count in the jail here, lifer Manabendra Baruah attacked constable Rituparna Chakraborty with a knife he was working with for cutting bamboo and cane to make furniture there.
While the policeman sustained wounds in his neck and head, another lifer Abdul Baten was injured when he tried to save Chakraborty, the sources said.

The constable was initially admitted to a hospital in nearby Gauripur but was referred to the Gauhati Medical College Hospital as his condition was serious.
Baten was admitted in the Gauripur hospital and his condition was stated to be out of danger, the sources said.
