Two streakers disrupted the Gent six day on Wednesday night, forcing organisers to delay the race programme while the two were held by Belgian police.
According to a report in Het Laatste Nieuws, the two streakers jumped onto the track during the musical interval and ran around the track naked.
A steward tried to stop one of the streakers and was apparently head butted. Plain clothed police officers then stopped the male streaker, while the steward was treated for a head wound. The huge crowd seemed fascinated by the additional entertainment during the evening's racing, giving the two streakers a cheer of support.
Iljo Keisse and Glenn O'Shea have taken the overall lead after another intense rivalry with world champion Gijs Van Hoecke and Kenny De Ketele. The Belgian/Australian pair lead by just six points.
