Sagan rapped for podium 'bottom-pinch' - FRANCE 24Sagan, 23, smirked towards the camera as he grabbed the bottom of a blonde hostess, one of two girls giving congratulatory kisses to race winner Fabian Cancellara.
His actions caused an out-pouring of anger on Twitter.
Jane Aubrey, editor of Australian website cyclingnews.com, also condemned Sagan's actions.
"Anyone excusing Sagan's behaviour due to his age, needs to think again. In the workplace, it's called harassment," she tweeted.
Sagan later took to Twitter to apologise for the incident.
"Was not my intention to disrespect women today on the podium. Just a joke, sorry if someone was disturbed about it," he wrote.
