Officials at the Louvre museum in France say a woman has vandalized one of its paintings.
Authorities say the woman was detained late Thursday after scrawling "AE911" on Eugene Delacroix's Liberty Leading the People
in a satellite branch of the Louvre in the northern town of Lens
. The meaning of the inscription was not immediately clear.
Museum officials say they believe the painting can be restored.
Authorities have ordered a psychiatric evaluation for the 28-year-old detainee.
Louvre officials say the incident will not affect their plans to display more of the museum's masterpieces with the Louvre-Lens gallery.
The Delacroix work is among the artist's most famous. It shows a bare-breasted woman holding aloft the French flag as she urges on a crowd of revolutionaries.
