Cars, money and jewellery have been seized in searches carried out by the Criminal Assets Bureau in Kildare and Dublin today.
Three houses and two businesses were searched this morning, leading to the seizure of an Audi A6 and a BMW 5 series, along with €4,000 in cash.
Three Rolex watches, a pair of runners worth €550 and two electronic weighing scales were also recovered.
More than €30,000 held in financial accounts was restrained on foot of orders granted as part of the operation.
Gardai say the Cab investigation is focused on an individual who is a member of an organised crime gang involved in the sale and supply of controlled drugs in the Dublin 8 and Dublin 12 areas.
