Harry Potter star Daniel Radcliffe features in controversial new stage play Equus.

One of the publicity photos shows a topless and buffed Radcliffe being hugged by a naked woman. Another shows him leaning against bales of hay as he stares up at the topless woman. A third has him posing in front of a white horse.

The pictures have been released ahead of the opening of Equus, a controversial Peter Shaffer play showing at London's Gielgud Theatre from next month.

Radcliffe,17, plays a troubled stablehand who one night blinds six horses with a hoofpick.

He features in numerous nude scenes with co-star Joanne Christie, the woman in the publicity shots.

The UK's Daily Mail reports that Harry Potter fan sites have received emails from concerned parents.
