The flamboyant designer was drinking at a bar in the Marais district of the French capital when he began verbally assaulting two strangers sitting on a cafe terrace, according to Britain's Guardian newspaper.
Galliano, the head designer of Christian Dior, was taken to a police station for a sobriety test. The state prosecutor recommended his release and charges were not filed. Cops later escorted the 50 year old to his home in the city.
The arrest comes just days before the launch of Paris Fashion Week, where couture house Dior's show is one of the main attractions.
