Police in Mankhurd have had to take help of a sketch artist in an effort to establish the identity of a woman whose highly-decomposed body was found from a nullah last month but a matching missing complaint record could not be found anywhere in the city, an officer said on Sunday.

The body of the woman, in her early 20s as per the post mortem report, was found on August 22 but the checking of scores of CCTV clips from the area as well as probe with people in the vicinity drew a blank about her identity, he said.
