Detectives are working with their counterparts in Ireland to root out the leaders of the feared cartel said to laying low in the West Midlands.
High-profile members of the Kinahan cartel, rocked by a series of arrests, are said to have fled to Birmingham in an attempt to rebuild their crumbling empire.
The Dublin mob made global headlines when a bloody, murderous underworld feud erupted with the rival Hutch mob – sparking a bitter rift played out in Ireland and Spain.
It has claimed 15 lives in the last three years alone.
And it comes as a fresh wave of violence and new brutal gangs have rocked the Irish capital, including the vicious killing of Keane Mulready-Woods.
The 17-year-old was kidnapped and dismembered before his body parts were dumped around the capital to send a message to rivals.
He is believed to have killed by gangs connected to Owen Maguire and Cornelius Price – while the Hutch and Kinahan gangs have been laying low.
Violence between the two gangs peaked on February 5, 2016, when gunmen opened fire during a boxing show weigh-in at the Regency Hotel, Dublin.
David Byrne, an associate of the Kinahans, was shot dead and two others were injured.
Irish online publication The Journal reports: “Police in Birmingham are working with gardaí as they attempt to dismantle some of the last strongholds of the Kinahan cartel in the UK.
“A number of senior members of the cartel had fled to the Midlands city in a bid to rebuild their crumbling empire since the successful prosecutions of many of the criminal gang’s main players.”
It added: “Gardaí and Birmingham police have shared intelligence on the gangs’ operations and are in the process of targeting the highest players in the criminal enterprises.
“The successful prosecution of top figures in the cartel such as that of killer Fat Freddie Thompson last year has left the organisation in pieces.”
The organised crime syndicate’s power has been threatened by a new rash of ruthless gangs springing up on the streets of Dublin.
At the start of 2019, Thomas “Bomber” Kavanagh, was detained at Birmingham Airport on suspicion of conspiring to import and supply drugs, firearms and ammunition, as well as money-laundering.
The arrest was part of a National Crime Agency investigation.
The 51-year-old was jailed for three years after a 10,000 volt stun gun, disguised as a pink torch, was found at his palatial home.
At Stoke Crown Court, he admitted having a stun gun, but denied possessing a device designed to look like a torch.
The Irish press described Kavanagh as a senior Kinahan cartel associate.
The illicit drug trade in Ireland has evolved into a multi-million dollar business.
Cops believe the new gangs have emerged to take over the trade which was once dominated by the Kinahans.
Mulready-Woods’ murder was seen as upping the ante for the gangs, with it believed that his head was supposed to be delivered to a gang boss.
His remains were found dumped in a housing estate, while his head was found in a burnt out car after he was abducted and butchered.
He is feared to be linked to both sides of the drug war and was said to be in over his head.
Police continue to probe the shocking killing, which is seen as an escalation even from the heights of the Kinahan-Hutch war.
Previously, one source told the Irish Examiner said: “This is a new level for gangs.
“Even the Kinahan cartel didn’t do this symbolic stuff in their killings.”
Another added: “It’s very sinister, very mafia-style.”
Other reports have said a gang boss linked to killing of Mulready-Woods is also believed to be in Birmingham.
