O’Sullivan recalls heroin haul swoop

- Emma Mcmenamy A Retired

A Retired cop has revealed how he became an undercover detective to take down heroin kingpin Larry Dunne.

Former Assistant Garda Commissioner Michael O’Sullivan became involved in the covert operation during the 1980s.

He was stabbed with syringes and had flesh bitten off during arrests when he worked in a unit known as “The Mockies”, who were fake drug addicts.

Speaking in the latest episode of The Case I Can’t Forget, O’Sullivan recalls the inside story of this ground-breaking investigation and explains how the case stuck with him for the rest of his career.

His investigation led to a four year game of cat and mouse as he set out to bring down Ireland’s first heroin drug lord.

O’Sullivan’s job was to pose as a drug user, infiltrate the upper echelons of Dunne’s gang, and gather enough evidence to arrest and charge him with drug offences.
