VeloNews | Belgian police stage raids; Museeuw questioned after search

An official at the public prosecutor's office in the western town of Kortrijk said detectives took Museeuw to headquarters for questioning. Spokesman Tom Janssens said police found quantities of suspicious drugs when they staged coordinated raids on the homes of professional riders.

"In all these places, substances were impounded," Janssens told Belgian television, adding that all of the impounded substances were currently undergoing testing.

Janssens said the raids were made following an investigation into hormones in the agricultural sector. A number of people were being interviewed, he said.

Investigators found that a local veterinarian was not only selling hormones for use in animals but were also being distributed among Belgian cyclists, he said.
