London, Nov 14 - 'Harry Potter' star Daniel Radcliffe is considering legal action to contest claims that he smoked cannabis at a party.

The actor was pictured in Britain's Daily Mirror newspaper Friday apparently smoking a roll-up cigarette, reports imdb.com.

The newspaper alleged Radcliffe had been puffing pot at the party - but his representative has denied it.

'We categorically deny the allegations regarding Daniel Radcliffe... Daniel does smoke the occasional roll-up cigarette, but he was not doing anything more than this. We are considering our position and will be taking all necessary action in relation to such allegations,' a representative of the actor has been quoted as saying.
