Bell missing from Hobart museum exhibit

Police are appealing for public help to find a bell stolen from an interactive artwork at Hobart's Mona museum.

The former Chinese cannon shell casing was one of four hanging beneath a trampoline near the museum's entrance and was taken overnight on March 15, Senior Constable Elise Allen said.

The large copper-coloured bell was part of an exhibit titled Danser La Musique, by a Chinese artist.
