Gardaí investigating the murder of Mark Desmond have made two further arrests this morning.
The men, both in their late 20s, were arrested by gardaí in the Clondalkin area in west Dublin.
On Tuesday a former criminal associate and close friend of Mark Desmond has been arrested by armed gardaí in relation to his murder.
Desmond, who was known as the 'Guinea Pig', was shot dead last December in a west Dublin park. He was the chief suspect in at least four murders and had been working for a drugs gang at the time of his killing.
Early yesterday, heavily armed gardaí raided two properties in west Dublin and arrested two men, one aged 39, the other aged in his 20s.
The Irish Independent can reveal that one of these men was a long-time associate of Desmond (41) and had been involved in the drug trade with him.
The 39-year-old man is also a target of the Criminal Assets Bureau (CAB) and his home was recently raided.
He is originally from the Clondalkin area but currently has an address in another part of west Dublin. The man was previously questioned in relation to a €3m drug bust carried out by the then Garda National Drug Unit.
However, he was never charged in relation to the seizure.
