The Paul Klee Center said the inflatable sculpture, created by U.S. artist Paul McCarthy, broke away from its anchor and drifted down the street, bringing down a power line and breaking a window at a nearby children's home before it was recovered, RIA Novosti, a Russian news agency, reported Thursday.

Museum Director Juri Steiner said officials have not yet decided whether the inflatable piece will go back on display following the July 31 incident.
