Father-of-one Adam Chadwick, 20, died after a shooting at the terrace house and police are hunting three masked men and a woman.

Detectives believe the killing may have been a case of mistaken identity and are trawling through CCTV from local cameras in the hope of trapping the gunmen.

The man heading the hunt for the killers, Det Supt Steve Payne, is desperate to trace anyone who saw the gang's blue Ford Focus getaway car between when it was stolen from Oatland Heights, Little London, on June 11.

Detectives want to speak to anyone who saw the three men and possibly a woman abandoning the car at the rear of houses on Chapeltown Road, Chapeltown, before running off.

They tried to set the vehicle alight before fleeing down Sholebrooke Avenue.

Early on June 24 a woman described as white, 28 years old, 5ft4 to 5in tall with dark brown hair, olive skin and dark eyes, called at houses in Clifton Mount asking for someone called Michelle. She wore a black fleece or cardigan over a black top.

But later that night she again knocked at the home of Mr Chadwick's sister Gemma's and three masked black men wearing green camouflage clothing burst in and shot him.

Anyone with information can ring police on 0113 241 3006 or Crimestoppers anonymously on 0800 555 111.
