Four legs of girls and other body parts were recovered from Madiyaon area and IIM Road here today, police said.
There is high possibility that the decapitated heads recovered yesterday from Sitapur and the body parts found in Lucknow are linked, DIG D K Chowdhury said.
Prima facie the girls were killed and their bodies chopped off by someone, police said, adding that they were trying to identify the bodies and match the different parts recovered.
"We are probing the matter. Clothes have also been found with the body parts recovered today. There is no missing report of any girl from the six neighbouring districts," Chowdhury said.
No arrests have so far been made in this connection, police said.
