Mr Gaunt told MailOnline today: ‘Our decision to do this has made a big difference – we’ve noticed a number of people we’ve stopped are no longer coming in.
‘But that’s just our store – they’ll be going elsewhere. I reckon the stock lost by businesses here across Truro will be more than £1million and that’s just us, and there’s no one visiting at this time of year.
‘This isn’t to do with the economy, or the cost of living, or people needing to feed their families – it’s to do with the fact the police have been doing nothing about the shoplifting problem for years.’
He says too many shoplifters are still avoiding prosecution even when amassing hoards of stolen goods with overall values running into four figures.
He spoke to then-Shadow Home Secretary Ms Cooper while she was on the campaign trail in Cornwall ahead of Labour’s election win on July 4 last year.
Mr Gaunt did welcome the Government’s vow to reverse the former Conservative administration’s £200-and-above threshold for prosecuting low-level shop theft.
He said: ‘I spoke to the Home Secretary and she’s aware of the situation, which is great – but we’re not using the legislation we already have, to prosecute offenders.
‘And the police don’t seem to be answerable to anybody. People no longer think it’s illegal to steal.’
Freedom of information requests earlier this year found that the Cleveland Police area had the highest crime rates per 1,000 people, across England and Wales
Chief Constable Amanda Blakeman, the National Police Chiefs’ Council (NPCC) lead for acquisitive crime, told the BBC they were ‘committed’ to cutting shoplifting and holding offenders to account.
She highlighted guidance in the Retail Crime Action Plan such as pursuing all ‘reasonable lines of enquiry and prioritising attendance in incidents where violence is involved or an offender has been detained’.
She also urged anyone to ‘prioritise their own safety’ and dial 999 if a crime is occurring.
Mr Gaunt dismissed her assurances, saying: ‘If you phone 999 to report a shoplifter, they’ll literally say to you: “Stop wasting our time, call 101.”
‘And that then takes a lifetime to get through and still no one comes.’
He described shoplifters’ reactions when faced with citizen’s arrest as ‘indignation more often than not’ – while will some threaten: ‘I’m going to put you down.’
Mr Gaunt added: ‘Sometimes it turns physical, although of course we want to avoid that – we’re not caped crusaders and we don’t want to get involved in trouble.
‘When I was threatened with a broken bottle, me and my three sons made our presence felt but we tried to keep our distance.
Mr Gaunt, 62, says he has faced threats of physical violence – as well as ‘indignation’ when thieves are challenging for taking items from his gift shops
July was the most common month for shoplifting offences, research has found
‘Then I later found police didn’t interview him for six months, even though he’s seen in the town every day, and he was never prosecuted for this crime. It’s ridiculous.’
He said shoplifters tended to be a mixture of young people, people with drug and alcohol addictions, and in one instance a young woman who was being run by a county lines dealer from Leicester.
After detaining her, she confided in him that the dealer had also made her smuggle firearms and perform sexual favours.
Mr Gaunt said: ‘People aren’t shoplifting in here because they’re starving.
They’re stealing any items they can sell, maybe at a local market, for cheap prices for cash which then goes on drugs.
‘All that money goes into more trouble – it goes into supporting low-level drug dealers, county lines drugs gangs.
‘I don’t want people thinking about a £20 teddy bear I’m losing – what I’m interested in, it’s time the police stepped up, learnt from past mistakes and urgently tried to do something constructive for us all going forward.’
Devon and Cornwall Police told the BBC it was committed to working with retailers and ensuring criminals faced justice, while deploying resources based on threat, risk and harm.

The force said: ‘We must prioritise attendance where violence is involved or a shoplifter is detained.’
MailOnline has contacted Devon and Cornwall Police for further comment.
The Home Office said the government was pursuing ‘strong action’, including getting rid of the £200 threshold and specifically criminalising assaults on retail workers.
A spokesperson also said: ‘The NPCC recommends only trained security guards detain offenders and forces will prioritise attendance at these incidents.
