After last year's raid, a preliminary investigation was initiated regarding doping allegations against the stable.

What today's police raid is about is not clear at this stage.

It was carried out by the Danish police on behalf of a French investigation.

- We have no further information about the operation, says Dannie Rise from the Danish police in a press release.

The stable must have cooperated well with the police and the raid was carried out for two hours.

No items were seized.

Cyclists 'and leaders' homes were also searched on Monday before traveling to the start of the Tour de France.
