[6] He has a sister Maria and his youngest sibling was David Byrne who was shot dead in February 2016 as part of the Hutch–Kinahan feud.
[6] Christy Kinahan was arrested and jailed in Dublin in 1997 after being linked to a batch of stolen cheques.
[6] Leadership of the gang passed to Freddie Thompson and Byrne and his associates started sourcing their drugs from elsewhere.
[6] Byrne and his close friend Liam Greenhalgh, the former Ireland under-16 football captain, carried out armed robberies on two shops in Dublin's south inner city in July 1998.
[6] On 23 April 2000, Trevor Donnelly and his partner Jennifer Doyle were involved in a row with three women in the Abrakebabra in the Crumlin Shopping Centre.
[6] Byrne arrived in his car and began beating Donnelly with a baseball bat, hitting him even as he lay on the ground.
[6] He wanted to avoid the Criminal Assets Bureau, the feud and to be closer to the European cocaine wholesale market.
[6] Within weeks of Kinahan's departure Brian Rattigan had fatally stabbed Declan Gavin.
[4] Gardaí watched and frequently stopped members of the gang, particularly Liam Byrne and Sean Gerard McGovern.
[4] In September 2000 senior member of the gang Liam Roe bought a house on Grangeview Road, Clondalkin for €119,000.
[4] His sister Maria was withdrawing €2,000 on the same date but didn't make a claim on the Clondalkin property in the High Court.
[4] The Criminal Assets Bureau discovered that Maria got the money when she sold a house in Ashbourne to sister Melanie Johnson.
[4] He lived there with his partner, Anita Freeman, who the CAB discovered was receiving local rent authority payments and then paying them into Liam's account.
[4] The Bureau determined that the house was bought for €155,000 - €150,000 from the Mule State Foundation and €20,000 from the car businesses that had been lodged to McGovern's account.
[4] Forensic analysis of McGovern and Freeman's means could not determine the source of the money used for the renovations.
[11] The CAB applied to the High Court to ask Maria Byrne to promise that the Raleigh Square house would be handed over intact.
[12] The CAB asked the National Crime Agency in the United Kingdom and they replied with information about two conspiracy investigations into drug smuggling from mainland Europe into Ireland and the UK.
[4] The first investigation, into industrial metal rollers that contained cocaine, cannabis and mixing agent led to the conviction of James Mulvey and Barry Kenneth Phibbs.
[4] Police discovered that the Mule State Foundation was established "for the educational benefit and wellbeing of the Mulvey family".
[4] The High Court gave the Byrnes four months to leave the Raleigh Square house and Liam had already left it for the UK by 3 September 2019.
[5] Police action against the EncroChat communications network resulted in messages relating to the Byrne organised crime gang being intercepted.
[14] Although Liam Byrne himself is not suspected of using Encrochat, the National Crime Agency has intercepted messages they believe were associated with his business operations in Birmingham and Liverpool.
[14] In the early hours of 12 August 2020 the house on Grange View Road, Clondalkin that CAB had seized from Liam Byrne was attacked by a car that deliberately reversed into the downstairs living room and then petrol bombed.
