A drug dealer sent to Swansea by a London gang had sold £16,000 worth of heroin and cocaine in just over a month, a court has heard.
Luis Migel Lemos Nunes was caught by police as he made a delivery to waiting addicts.
On his phone officers found evidence of the scale of his dealing in the previous weeks.
His arrest led to the capture of another London dealer, Raysharn James, who was also wanted by police in Bournemouth after dealing on the south coast.
The jailing of Nunes and James at Swansea Crown Court is the latest in a string of convictions in so-called "county lines" cases which involve organised criminal gangs from large English cities such as Liverpool and London extending their operations into Welsh towns and cities.
Prisoner 'pulled drugs out of his anus and forced cellmate to swallow them'
Jim Davis, prosecuting, told the court that on April 4 this year South Wales Police officers were working covertly in the Cwmbwrla area of Swansea, investigating a drug-dealing gang they had dubbed the "Pablo line".
The officers began monitoring a group of people they believed were waiting for a delivery of drugs.
The prosecutor said as Nunes approached the group the officers heard someone shout "he's here now", and they moved in.
Nunes made off, but was caught a short distance away.
When searched the 39-year-old was found to be in possession of two packages of cocaine.
The court heard when officers searched the property Nunes had been using on nearby Carmarthen Road they found keys to a flat in Gordon Morris Close in Waun Wen - when officers raided that address they found 20-year-old James laying on a bed in the property, along with 77 wraps of heroin and cocaine, weighing scales, dealers notes showing amounts owed, and £1,700 in cash.
Mr Davis said it was the prosecution case that the wraps of drugs belonged to both men.
When Nunes' mobile phone was checked officers found a "considerable amount" of messages about dealing which showed some £16,000 worth of drugs had been sold between February 18 and March 23.
The court heard that at the time he was caught in Swansea , James was wanted by police in Bournemouth having skipped bail following his arrest for possession with intent to supply in July 2017.
Nunes, of Carmarthen Road, Cwmbwrla, Swansea, had previously pleaded guilty to possession of crack cocaine with intent to supply, being concerned in the supply of crack cocaine, and being concerned in the supply of heroin when he appeared in the dock for sentencing.
James, of Sedum Close, Brent, London, had previous previously pleaded guilty to possession of crack cocaine with intent to supply, possession of heroin with intent to supply - offences committed in both Swansea and Bournemouth - being concerned in the supply of crack cocaine, and being concerned in the supply of heroin.
Nunes has previous convictions for dishonesty matters including theft and handling stolen goods.
James has no previous convictions.
Huw Davies, for Nunes, said his client had moved to the UK from his native Portugal in 2011 and worked as a chef in London.
The barrister said Nunes began to use Class-A drugs and quickly became addicted and then indebted - and when his dealers "suggested" he go to Swansea to sell drugs to pay off his debts he felt threatened into doing it.
Mr Davies said Nunes had been in Swansea for around four months before his arrest.
Drug dealers advertised themselves as 'Deliveroo' service for heroin and cocaine
Dan Griffiths, for James, said his client had left home after a breakdown in his relationship with his mother, and he had found himself "sofa surfing" with friends and spending his days hanging around his local McDonald's restaurant.
It was at the burger bar that members of a gang "took him under their wing", offering him food and somewhere to live - but expecting something in return.
The advocate said Raysharn was sent to deal in the Bournemouth area then, following his arrest and the seizure of the drugs he had on him, was told "in no uncertain terms" that he had to make-good the "loss" the gang had suffered - and was sent to Swansea.
Mr Griffiths said: "He became entrenched in further drug dealing. He was risking everything for very little personal financial gain."
Judge Keith Thomas told the defendants that Class-A drugs were a serious problem in the community, and the sentencing guidelines made it clear that those who dealt them would almost inevitably receive custody.
Giving Nunes a one-third credit for his guilty pleas the judge sentenced him to three years in prison.
Giving James credit for his guilty pleas - which were entered later and therefore attract a lesser discount - he sentenced him to 81 months in prison.
