The arrest of a suspected key figure in the Kinahan cartel in Marbella has emerged as the pivotal breakthrough that led to the dismantling of the powerful Lyons crime clan on the Costa del Sol.
According to police sources, the capture of Johnny Morrissey provided crucial intelligence that ultimately fed into the operation against the group allegedly led by Steven Lyons.
The British national of Irish origin was described by investigators as a central financial operator within the Kinahan network.
Arrest that changed everything
Morrissey was arrested in September 2022 in an apartment near Marbella during a Guardia Civil raid led by its elite Unidad Central Operativa (UCO).
His wife, Nicola, was also detained as part of the same investigation into alleged money laundering and organised crime links. Both remain under investigation and are currently on bail.
The operation was built on intelligence gathered from EncroChat, the encrypted messaging platform widely used by criminal networks.
It was was infiltrated by law enforcement between March and June 2020, giving investigators unprecedented access to real-time communications.

Two operations, one network
Police sources say the operation targeting Morrissey – known as Operation Whitewall – and the later crackdown on the Lyons clan, Operation Armorum, were ‘intrinsically linked’.
‘Operation Armorum comes from Operation Whitewall,’ one source told Area Costa del Sol, confirming that intelligence obtained from Morrissey’s activities directly fuelled the case against Lyons.
Investigators believe Morrissey and Lyons relied on each other’s services, forming part of a wider criminal ecosystem that extended beyond the Kinahan cartel.
While Morrissey was labelled the cartel’s ‘banker’, police suspect his financial network may have supported multiple organised crime groups operating across Europe.
€350,000 a day laundering network
At the time of his arrest, authorities alleged Morrissey helped launder up to €350,000 a day over an 18-month period.
The system used was believed to be hawala – an informal and highly secretive money transfer method that bypasses traditional banking systems through networks of trusted intermediaries.
Transactions can be verified using codes, signals or even split banknotes, making them extremely difficult to trace.
Investigators also allege Morrissey used a drinks company, Nero Drinks, as a front to conceal illicit activity.

Lyons clan under the spotlight
The Lyons group, which police say laundered more than €30 million, is accused of using a web of businesses, including food and drink companies, car rental firms and leisure ventures, to give a veneer of legitimacy to criminal profits.
Operation Armorum resulted in 15 arrests, including Amanda Lyons, with further detentions in Spain and Scotland.
Lyons himself was tracked across multiple countries before being arrested following his deportation from Bali and subsequent detention in Amsterdam under a European Arrest Warrant.
He now faces extradition to Spain, where a judge in Malaga is preparing to question him over alleged money laundering and organised crime offences.
International web of crime
The case against Morrissey, meanwhile, remains open and is described as highly complex due to its global reach.
Spanish investigators have sought cooperation from authorities in Dubai – long believed to be a base for senior Kinahan figures – as they attempt to piece together the full financial structure of the network.
Morrissey had already been flagged by the US Treasury as a key member of the Kinahan cartel, accused of facilitating international drug shipments and laundering proceeds across borders.
His arrest marked a dramatic fall from a life of luxury, from multimillion-euro villas and celebrity circles to a prison cell following a dawn raid on the Costa del Sol.
