"At 2.45 pm, an individual was seen climbing the Eiffel Tower. The police immediately intervened and arrested the individual," a police spokesman said.
Videos posted on social media showed the bare-chested climber skirting the Olympic rings as he made his way up without ropes. In one, the grinning climber can be heard saying to bystanders "bloody warm, innit?" as he is escorted off the viewing platform by police.
The tower operator did not respond to a request for comment.
