Specialist firefighters were on the scene, the police spokeswoman said.
“The man entered the tower normally and started to climb once he was on the second floor,” a spokeswoman for the tower’s operator told Reuters.
Tourists at the scene said they didn’t know much about the situation except that there was a man climbing the tower.
The tower, one of the world’s most recognizable landmarks, will be closed until further notice, the company added in a statement on its official Twitter handle.
