Input: Police shot Mudasir  accused of killing five-year-old Iman Fatima  in February 2017  saying he tried to escape.
However  a BBC Newsnight investigation has uncovered allegations that  Iman 's real killer is still at large.
DNA tests suggest  Iman  was killed by the same man suspected of murdering another child this month.
Until now  police and  Iman's  family thought  her  case had already been solved - but  her  family now believe the real killer is still on the run  while Mudasir was innocent.
 Iman Fatima  had been playing outside in the street with  her  five-year-old cousin Adeel.
Sitting next to his father  Adeel told the BBC  "The kidnapper made me stand against the wall and took  Iman Fatima  away. He took  her  upstairs  put  her  in a sack and took  her  away."

After the discovery of  Iman Fatima 's body local residents began to protest against the perceived inaction by authorities. A month earlier in January 2017  another 5-year-old girl  Ayesha Asif had also been sexually assaulted and murdered.
Mudasir's family say he was taken into custody the same evening  Iman Fatima  was abducted and killed. They allege they then went with police to recover his body from a local hospital.
Speaking to the BBC   a relative of Iman Fatima  said police had called  him  into the police station to hear Mudasir confess to the killing.
Following Mudasir's death in February 2017  another four young girls were attacked  including Zainab. Three of them died  one is still in hospital. Traces of the same DNA were found on their bodies as of  Iman Fatima .
 Iman Fatima's  father told the BBC  "I'm so worried - the real killer is still roaming free  and an innocent man has been killed."
