18-year-old Belgian backpacker, Theo Hayez, has been missing for the last 18 days, last seen in Byron Bay at Cheeky Monkey’s.

9 News Queensland reports below, as his father pleads for his son to be found, as he promised Theo’s little brother that he would “bring his brother home.”

Hayez was supposed to fly home in early June, but he never returned to his Byron Bay backpacking accommodation after a night out in late May.

Heart wrenching.
