AGARTALA, Dec 20 (TIWN / IANS) A 60-year-old tribal woman in Tripura was beaten mercilessly and left unconscious by some people who accused her of having an illicit love affair, the police said on Sunday.

The woman was rescued on Saturday morning and taken by her neighbours to a hospital where her condition was stated to be critical.

The incident took place in Ujan Chandrapur village under Puratan Raj Bari police station of South Tripura district late Friday evening.
