Defacement of French painting 'completely removed'

Specialists have been able to "completely remove" marks left by a defacement of one of the most iconic paintings in French history, the Louvre said on Friday.

A 28-year-old woman, who officials said had psychiatric problems, was being held by police after allegedly using a black marker to deface Delacroix's "Liberty Leading the People", on display at a satellite branch of the Louvre in Lens, northern France.

"The integrity of the work has not been affected, as the inscription was superficial and remained on the varnished surface without reaching the layer of paint," the Louvre said in a statement.
