A man has been found guilty of using a YouTube how-to video to make a gun which left a shooting victim fighting for life after he was badly injured in Holmfirth.

Convicted drug dealer Neil Hazelwood was kidnapped and blasted in the chest with the ‘home-made lethal weapon’ after refusing demands to give his captors £100,000 in September last year.

Michael Sierotko, of Sunlaw Street, Glossop, made the crude ‘slap gun’ from pieces of metal piping according to online instructions.

He has now been found guilty of manufacturing a firearm at a Manchester Crown Court trial.

Sierotko was also found guilty of conspiracy to blackmail. However, the 24-year-old was cleared of attempted murder and conspiracy to kidnap.

Co-defendant, Anthony Leonard, 26, of Mouselow Close, Hadfield, Glossop, was cleared of attempted murder, conspiracy to kidnap, and blackmail.

Victim Mr Hazelwood was taken from his home in Whitefield, near Bury, to Hagg Wood in Holmfirth, where he was threatened and shot, leaving him needing six weeks of hospital treatment. The pair were arrested after being linked to Mr Hazelwood’s stolen Ford Focus.

Sierotko will be sentenced on September 19.
