Seven Hells Angels bikers – including two from Slough – have been convicted of brutally stabbing and battering members of a rival biker gang – that left one man disembowelled.

Przemyslaw Korkus, 41, of Penn Road, and Bartosz Plesniak, 34, of Lancaster Avenue, were part of a gang of 13 who targeted members of the Warg Brotherhood and Vikings Motorcycle Club at their weekly meeting.

They stormed an outbuilding at the Forman Club and Institute in Blindley Heath, Surrey, dressed in balaclavas and dark clothing just before 7.30pm on November 7, 2018.

Other victims were stabbed in the heads and back during the vicious attack.

Seven linked with the notoriously violent Hells Angels and its support motorcycle club Red Devils were found guilty of a string of assault and weapons offences after a trial.

It is thought the attack may have part of an initiation ritual after the attackers were found to be members or prospective members of the clubs.

When police reached the Forman Club and Institute, they found one man stabbed through his right arm and another with lacerations to his stomach which required bowel surgery and 29 stitches.

Others had bruising and stab wounds on their heads, legs and buttocks, Kingston Crown Court was told.

Korkus, the first of the seven defendants, who also goes by the name Przemyslaw Piwonla, was arrested in his home town of Slough within 24 hours after witnesses gave a description of his vehicle.

The others were eventually identified with Automatic Number Plate Recognition, CCTV footage and mobile phone data.

The seven defendants, aged 28 to 44, and from areas in Berkshire, north and west London, and Haywards Heath in West Sussex, were jointly charged with six counts of causing grievous bodily harm with intent, one of violent disorder, assault occasioning actual bodily harm, possession of a weapon and possession of a blade.

Detective Chief Inspector Chris Friday, who led the investigation, said: “This was a planned, unprovoked attack and these seven men knew what they were getting into when they met up that evening.

“Whilst they may try to justify their brutal actions as part of a feud with the Viking motorcycle club, and the prospect of an enhanced reputation amongst their so-called 'brothers', there is no excuse for this sort of gratuitous criminal violence in the UK.

“I hope these convictions serve as a warning to anyone who believes their loyalties to any group or gang justifies criminality or violence that we will do everything we can to disrupt and detect their activities.

“I am extremely proud of the professionalism and dedication of the team that has bought this case to court. It has been a painstaking inquiry, bringing together many bits of disparate information and piecing them together to create the case that convinced this jury.

“I also want to pay tribute to the witnesses who bravely stepped forward to share information, who gave evidence in court, and who have been instrumental in getting this result."

Przemyslaw Korkus, 41, of Penn Road, Slough, David Jacobs, 28, of Chalfont Lane, Rickmansworth, Bartosz Plesniak, 34, of Lancaster Avenue, Slough, Ladislav Szalay, 32, of Torrington Drive, Harrow, Tamas Tomacsek, 38, of Milton Grove, Enfield, London and Piotr Zamijewski, 44, of Dorchester Waye, Hayes, Hillingdon, were found guilty of all counts after an eight-week trial.

The last defendant - Jimi Kidd, 39, of Buttinghill Drive, Haywards Heath - was found guilty of all counts except possession of a weapon or blade.

The men will be sentenced at a date to be confirmed in October.
