KIERON Ducie, who was given a suspended jail sentence this week for organising another man to supply cocaine to model Katy French, used a garda ID badge to masquerade as a detective.
The Irish Independent can also reveal that the scrap dealer and socialite had blue flashing lights fitted in his jeep and pretended to be a member of the Garda National Drug Unit and the ERU.
Ducie admitted to using the blue lights on the morning he rushed Katy to hospital after she collapsed from a cocaine overdose in his house.
On Tuesday, Ducie (43) and his former partner Ann Corcoran were given suspended jail terms of two-and-a-half years and two years respectively after they admitted procuring Russell Memery to supply cocaine to Katy on the night before she died from an overdose.
Gardai found the official ID card when they searched his home in Kilmessan two days after the 24-year-old model fell into a coma in December 2007. Ducie had his own photograph and name superimposed over those of the young garda officer who actually owned it.
The card was then traced to the serving garda officer, a friend of someone known to Ducie, who had reported the card stolen nearly four years earlier. The officer had been extremely concerned and worried after the ID went missing.
The Irish Independent has learned that a number of witnesses told investigating gardai that Ducie had identified himself as a detective by producing the ID in a number of nightclubs.
In one club in Navan, he produced the card to security staff and claimed to be in the ERU and to be there to protect the daughter of a high ranking garda. On another occasion elsewhere, he said he was the Commissioner's driver and claimed to be investigating drug dealing.
Ducie's scrape with the law this week was not his first.
Two years ago, he was convicted of assaulting a garda when he was arrested at a nightclub in Dublin.
And last year, he was given 240 hours of community service after pleading guilty to an assault on his current partner, Elaine Buggle, with whom he has two children.
Katy's family revealed that they will never forgive Ducie and Corcoran following the hearing in Trim Circuit Court this week.
Her mother Janet said that they were "saddened" and "really angry" after more serious charges connected with Katy's death were dropped by the State.
And she said that her daughter's former friends left court with several unanswered questions.
In particular, the family want to know what happened during a period of one hour and 45 minutes from when Katy was found to her being brought to hospital in Navan – a journey that took Ducie just 12 minutes to make.
