A door decorated with a mural by Banksy has been stolen from Paris' Bataclan theatre where Islamist militants killed 90 people three years ago, representatives of the venue say.
The artwork by the mysterious street artist was one of a series of murals painted last June in the French capital and attributed to Banksy.
It showed a veiled female figure in a mournful pose.
"We are today filled with a deep sense of indignation," the Bataclan said in a Twitter post.
"The work of Banksy, a symbol of contemplation belonging to all - residents, Parisians and citizens of the world - has been taken from us."
According to a police source, thieves with a van had stolen the door on which the mural was painted.
The Bataclan theatre was stormed by militants during a rock concert in November 2015.
This was part of a number a coordinated attack in and around Paris that killed 130 people.
Some of Banksy's works in Paris, which also addressed issues like immigration, were vandalised soon after they were put up.
Others were protected by screens.
The murals of Banksy, who keeps his real name secret, have become prized attractions for collectors.
A work created last month in an industrial town in Wales, depicting a child enjoying snow that is in fact pollution, was sold for more than £100,000.
