As many as 120 undertrials have been ordered to be released from different jails in Maharashtra's Thane district since March following the launch of a scheme that aims at providing free legal services, an official said on Wednesday.

These undertrials, aged between 18 years and 70 years, have been in jail since nearly seven years without bail due to reasons like lack of knowledge about the procedure, inability to pay for it or kin not showing any interest in their release, the official said.
