The mysterious Banksy posted on his Instagram page Thursday showing his signature rat, this one running in a clock, tagged on a bank building on 14th Street and Sixth Avenue in Manhattan.

That building is set to be demolished.

Banksy's other piece appeared at the intersection of Houston Street and the Bowery this week.

The mural protests the imprisonment of a Turkish artist and journalist, Zehra Dogan. Dogan, an ethnic Kurd, was jailed after painting the Turkish flag flying over the rubble of a destroyed town, according to the Associated Press.
