Two American tourists were found sleeping off a heavy night in the heights of Paris’ Eiffel Tower on Monday, after dodging security the night before, the monument’s operator said Tuesday.

Security guards roused the men “in the early morning” as they were making their rounds before the French landmark’s opening at 9 a.m. local time, publicly-owned Eiffel Tower operator Sete said.

They “appear to have got stuck because of how drunk they were,” Paris prosecutors told AFP.

The inebriated Americans had spent their illicit night under the stars in a spot normally closed to the public between the tower’s second and third levels, but “did not pose any apparent threat,” said Sete.

After paying for an entry ticket around 10:40 p.m. local time on Sunday, the pair hopped security barriers while climbing down the stairs from the tower’s top, a police source said.

Firefighters, including a specialist unit for recovering people from dangerous heights, were sent to recover the interlopers, the police source added.

Both men were brought to the police station in Paris’ seventh district for questioning. Sete said it would file a criminal complaint.
