That’s just bull!

Wall Street’s beloved bronze bovine was set free yesterday (inset) for his 22nd birthday — but recaged an hour later (pictured) by the NYPD.

The “Charging Bull” sculpture has spent the last three months behind barricades erected to protect it from Occupy Wall Street protesters. The cage was briefly removed yesterday morning so locals could celebrate — which they did by groping the bovine’s rear end.

Eventually, the NYPD — reneging on a promise to community leaders to free the bull — put the barriers back up.

“They wouldn’t do this about the Statue of Liberty or Rockefeller Center!” protested Arthur Piccolo, head of the Bowling Green Association.
