More than £67,000 of ill gotten cash and thousands of pounds of drugs were found stashed in a caravan.
Stab vests, a knuckle duster, scales and bags were also discovered when police swooped at Flints caravan park on River Road, Thornton.
It came after officers caught Terry James Barlow, who was living at the site, and accomplice Jamie Giles, of Platt Street, Blackpool, supplying cannabis in the resort.
Preston Crown Court heard a police officer stuck in traffic happened to see Barlow, 39, behind the wheel of his dad’s car on Hornby Road – just as Giles, 26, exchanged drugs for money out of the car window.
Barlow admitted possessing a class B drug with intent to supply and two counts of possessing criminal property in relation to the money, and was jailed for 21 months.
Giles (pictured) admitted supplying cannabis, possession with intent to supply cannabis, and possessing criminal property and was jailed for 16 months.
Recorder David Swinnerton said: “The sheer amount of money indicates this has been going on for some time.
“Cannabis is a menace. It itself destroys lives, particularly with the stronger strain on the streets, and I’m assured in both your cases the sentence has to be immediate.”
He also told Barlow he should be ‘thoroughly ashamed’ after it emerged his dad, who is in his mid 70s, was initially arrested when officers traced the details of the car Barlow had been using.
Prosecuting, David Clarke said the officer had alerted colleagues after spotting the drug deal from a Peugeot.
He added: “Around 90 minutes later PC Smith saw the car parked on Albert Road. He followed it to a few streets away to George Street.
“Officers approached the car and invited Mr Barlow and his passenger to get out, however there was a lack of cooperation and a stand off.
“Mr Barlow made a phone call to a man called Danny and only when it ended did he turn the engine off.”
Officers found £1,983 and a Samsung phone on Barlow, while Giles was found to have £475 after being searched. A further £3,000 was found in the glove box, and £3,050 of cannabis in the car.
The duo refused to give ID or their names and police traced the details of the car - which was Barlow’s elderly father’s. The pensioner was initially arrested and he told them his son lived on the caravan site.
Officers found £67,566 and Euro notes worth £592 with £1,000 of cannabis and mobiles phones containing incriminating messages.
The court ordered the cash to be forfeited but it is understood no Proceeds of Crime probe will take place.
