DETROIT - A 12-year-old visitor to the Detroit Institute of Arts stuck a wad of gum to a $1.5 million painting, leaving a stain the size of a quarter, officials say.

The boy was part of a school group from Holly that visited the museum on Friday, officials say. They say he took a piece of Wrigley's Extra Polar Ice gum out of his mouth and stuck it on Helen Frankenthaler's "The Bay", an abstract painting from 1963.

Holly Academy director Julie Kildee said the boy had been suspended from the charter school and says his parents also have disciplined him.
