UCI president Brian Cookson revealed the governing body is trialling new methods of detecting "technological fraud" amid allegations of an engine being fitted to a bicycle at the Cyclo-cross World Championships

The UCI has launched an investigation following claims that regulations were breached during the women's under-23 race in Belgium on Saturday.

A UCI statement said: "The Union Cycliste Internationale (UCI) confirms that pursuant to the UCI's Regulations on technological fraud a bike has been detained for further investigation following checks at the Women's Under-23 race of the 2016 UCI Cyclo-cross World Championships.

"This does not concern any of the riders on the podium. Further details will be shared in due course."

Cookson offered an update when he spoke to the media on Sunday.

"We've been trialling new methods of detection but you'll understand why I don't want to go into details of those methods." he said.

"Throughout the 2015 season, we carried out unannounced bike checks at major Road events and we will conduct similar controls throughout the 2016 season."
