The English tourist — Ivan Dimitrov — who was filmed apparently carving his name into a wall of Rome’s 2,000-year-old Colosseum has sent a letter of apology to the local prosecutor’s office, his defense lawyer told CNN on Thursday.

“I admit with the deepest embarrassment that only after what regrettably happened, I learned of the antiquity of the monument,” he wrote.

The idiot tourist could face a fine of  5,000 euros ($5,400) and 15 days in jail.

As you can see in the video, filmed by another (horrified) tourist showed he used his key to scratch “Ivan + Hayley 23” into the 2,000-year-old UNESCO World Heritage site last month.
