Gardai have seized three quarters of a kilogramme of cocaine from a house in Terenure this afternoon.
The drugs are believed to be worth approximately €38,500, but Garda sources have not confirmed earlier reports that a 'mixing factory' was also uncovered at the scene.
A 46 year-old Englishman is in custody at Pearse Street Garda station under Section 2 of the Drug Trafficking Act, where he can be held for up to seven days.
