Nazi Southport rioter called Dunblane massacre ‘a waste of a mass shooting’

A man who threatened several police officers and took part in the Southport rioting was found with Nazi materials and weapons at his home.

Jack Mason used the pseudonym Harry Roberts, the name of a serial killer who killed a number of police officers, to send several threatening emails to members of Merseyside Police.

He told Chief Constable Serena Kennedy that he had a gun and would ‘cut her face off’ during the Southport rioting last summer.

31-year-old Mason had previously been detained for ‘obstructing a drug search and resisting arrest’ in 2021.

He then bombarded the arresting officer with threatening phone calls, telling him ‘I’ll just f***ing blow your head off, you little d***head,’ in one call.

Mason was convicted of harassment and handed a restraining order which banned him from contacting the arresting officer until June 2022.

The officer left Merseyside Police, but his collar number was given to a new PC and Mason used it to email him on February 7 of last year.

Using the Harry Roberts moniker, at first he claimed he wanted to share evidence in relation to a case, but this was shortly followed up by another email which said: ‘Come on now Jack, don’t be ignoring me you stupid b*****d”.

‘Soon, people will die. When it’s all over the news, I want you to think back to this lovely email and when you see my name it’ll all make sense.’

In a third email, all sent on the same day, Mason said: ‘I only hope you would be there on the big day, but the odds aren’t in my favour. Either way I will be tasting blood, even if it’s not yours.

‘Recipe: two Glocks, one .38, eight magazines, one uniform, one stab proof vest, one bottle of petrol, one lighter, one police station.’

Mason was arrested on March 1 after sending a further email on February 17 warning ‘time is almost up’ – however, no action was taken against him, as police couldn’t find evidence linking him to the Harry Roberts emails.

He later took part in rioting in Liverpool city centre on August 3, after an attack in which three young girls were killed.

Mason asked an acquaintance the day before: ‘Do you know where there’s any protests meeting up?’

He added it was ‘kicking off in Sunderland already’ and remarked that there were some ‘[racial slurs] in Liverpool as well’, saying: ‘Going to town tomorrow, I just want to know where. Is it definitely at the Town Hall tomorrow?’

On the day of the rioting, Mason was caught on camera smashing bricks onto the floor on the Pier Head and launching a missile towards police officers.

In this footage, he was shown with a balaclava covering his face and wearing the same khaki green shirt that he wore in the dock.

Less than a fortnight later, on August 15, Mason sent more emails under the Harry Roberts pseudonym, this time to Chief Constable Serena Kennedy.

He told her ‘One gun acquired, two more to go. It will be a glorious day,’ then emailed another officer the next day asking how it would feel to watch Chief Constable Kennedy’s face being ‘cut off’.

Mason added killing officers would be a ‘dream come true’ and described the killing of 16 children in Scotland as a ‘waste of mass shooting’.

This appeared to be a reference to the Dunblane massacre, in which 16 children and a teacher were shot dead at a primary school in 1996.

Mason was then further arrested on September 18. While searching his home, officers found an airsoft gun, a noose, a knife, a drawing of a swastika, stickers bearing the words ‘white lives matter’ and racial slurs, two suicide notes and a small quantity of cannabis.

Pictures of the defendant wearing a swastika armband, a photograph of a rainbow flag being burned and an image containing the message ‘don’t blame me. I voted for Hitler’ were found on his phone.

Mason has a total of five previous convictions for seven offences, including two appearances for resisting police in 2022.

He faced a malicious communications offence later that year after threatening to ‘attend St Helens Police Station with a firearm’.

In January 2023, he was handed an 18-month community order for a similar charge after sending a series of texts to a female police officer in which he said he was ‘intending to purchase a firearm’ and was ‘thinking of going shooting police officers at the police station’.

Paul Becker, defending, told the court on Monday that the death of Mason’s father had led to a ‘significant effect on his mental health’, with his client having shown ‘suicidal and autistic traits’.

Mason, of Grasmere Avenue in St Helens, pleaded guilty to violent disorder, five malicious communications offences and possession of cannabis.

He showed no reaction at Liverpool crown court as was jailed for four years and four months and handed a five-year criminal behaviour order.

Sentencing, Judge David Potter said: ‘You knew that Harry Roberts was a figure from the 1960s who had murdered police officers, and you assumed that person’s name deliberately.

‘You told the officer that you were wanting to get in touch over some evidence however, the following day, you began the first of several threatening messages.

‘Following your participation in the violent disorder, your threats substantially increased and now targeted the Chief Constable of Merseyside Police, Serena Kennedy.

‘Your email contained a specific and detailed description of the violence you wanted to commit upon Chief Constable Kennedy.

‘It was a direct threat to life. While she of course requires a strong degree of resilience to carry out her duties, she nonetheless is human and threats like this are pervasive and intrusive.

Of Mason’s involvement in the violent disorder, the judge added: ‘I am satisfied that your offending was motivated by religious or racial hatred.

‘You plainly attended these protests because of a deep seated hatred of Islam and non-white ethnic groups.’
