Some visitors to a new exhibit at New York City's Museum of Modern Art are being asked to leave because they are touching nude performers.

The performers featured in Marina Abramovic's new exhibition have complained of being pushed, prodded, and poked by some patrons.

The museum acknowledges that it has had problems with some visitors touching the live art. It is declining to talk about specific cases, but says visitors caught doing it are escorted out.

The exhibition opened March 14 and presents a view of Abramovic's career over four decades.

It includes nude performers standing in a narrow doorway that visitors can pass through. Elsewhere, a naked woman reclines with a fake skeleton on top of her. Other live performers are clothed.
