Ali Williams arrested in Paris, allegedly tried to buy cocaine

Former All Black Ali Williams has been arrested after allegedly being caught trying to buy cocaine.

He was apprehended outside a nightclub in Paris by officers from the French Anti-Crime Brigade, along with former Wallabies international James O'Connor.

The pair were allegedly handing over cash to a drug dealer in the early hours of Saturday morning (France time).

A judicial source said both players were drunk at the time of their arrest and were not carrying identification papers.

The source added that they were attempting to buy drugs worth about $200 and that the two sellers were also arrested.

Williams, 35, currently plays with French club Racing 92, while O'Connor, 26, plays for Toulon.

Racing 92 said in a statement that it had suspended Williams over the incident.

"It was decided to temporarily suspend Ali Williams. If the investigation confirmed the possession of cocaine and the transaction, it would not only be against the law but also a serious breach of our ethics," the club said in a statement.

Toulon could not be reached for comment.

New Zealand Rugby declined to comment on Williams' arrest, saying he was "no longer contracted to New Zealand Rugby so queries should be directed to his current club Racing 92 or his agent".

But it did have something to say on drug use.

"New Zealand Rugby takes the issue of illicit drugs very seriously," said general manager Neil Sorensen.

"In our last players' collective agreement we introduced a new illicit drugs test regime and we promote and expect drug-free sport."

Illustrious career

Williams played for the All Blacks 77 times in his decade-long international career, which ended in 2012.

O'Connor earned 44 caps with the Wallabies between 2008 and 2013.

The arrests come less than two weeks after former All Black Dan Carter was caught drink driving, also in Paris.
