A Manhattan installation by the anonymous graffiti artist, Banksy, has been restored after it was found tagged by a vandal.

Red graffiti was found Saturday across the bottom of the 70-foot-long mural that the anonymous Banksy created in the East Village. By Sunday, the graffiti was painted over.

The mural is an artful protest of the imprisonment of a Turkish artist and journalist.

The mural bearing the slogan "Free Zehra Dogan'' was recently installed on the Houston Bowery Wall, made famous by Keith Haring in the 1970s.

The mural protests the jailing of Dogan, an ethnic Kurd, after she painted the Turkish flag flying over the rubble of a destroyed town. Dogan was convicted last March.

Banksy's mural shows her jailed behind a set of black tally marks representing her days in prison.

The mural is one of two new Banksy installations that have recently popped up in the city.
