The mutilated body of an eight-year-old girl was recovered from the busy TT Nagar area, located close to Gupta's residence, in Bhopal on Monday.
The girl had gone missing on Sunday evening after she went to the Bhopal Utsav Mela, following which her parents lodged a missing person's report with the local police.
The body was found near debris of dismantled houses in the north TT Nagar area.
Singh said the incident was an example of the manner in which the law and order situation in the state had collapsed.
The ruling BJP in Madhya Pradesh has always been making tall claims about controlling the law and order situation in the state, he alleged.
"This incident alone shows the hollowness of the claims made by the BJP," Singh said.
Singh also expressed concern over the fact that the culprit was not arrested so far.
