Tourist spends night trapped in Milan's Duomo cathedral

The caretakers of Milan's historic Duomo cathedral on Wednesday requested additional police surveillance in light of an incident in which an American tourist was locked inside overnight and the terror attack on a French church.

Italian police say an American tourist spent a night locked on the spectacular rooftop of Milan's Gothic-inspired Duomo after being overlooked by security.

Police said the 23-year-old holidaymaker told them that he was in the bathroom when security made a final pass and found himself locked inside the landmark cathedral when he went to leave on Monday night.

He decided not to create alarm and spent the night on the spired rooftop, reporting himself to authorities when they reopened on Tuesday morning.

The tourist, from Illinois, did not face any charges and authorities declined to identify him.
