Footage shows a man pacing up and down on the roof of the Opera House, with police called to the scene.

A MAN has been rescued after he climbed to the top of the Opera House this afternoon, to the shock of witnesses below.

news.com.au reader Marek Kopias said that police arrived at the scene promptly: “Police rescue have just rocked up,” after the man was seen up there.

“He was yelling out ‘where’s my wallet?’ Pulled a beer out of his pants and has been pacing up and down.”

According to police this was not a protest, but simply, “a drunken guy (who) just decided to go up the sails”.

The man was on the roof for around an hour before Police Rescue brought him down.
