Ian Bailey was suspected of being over the drink-driving limit when he was stopped by Gardai last week, we have learned.
The man previously suspected of involvement in the Sophie Toscan Du Plantier murder received the results of his urine sample taken by Gardai in the last few days and it's believed it was positive for the presence of alcohol.
He was stopped by road traffic police near his home outside Bantry, Co Cork last Sunday week as he made his way back from a trad-fest in Schull.
