The singer told Radio Times he had "never said this before", adding: "Should I be saying it now?"
"A man tried to molest me when I was about four-years-old," Gibb explained.
"He didn't touch me, but other things happened and happened to other kids. And eventually they came and arrested him, and woke me up during the night."
He added: "Four years old and a policeman on your bed at four in the morning interviewing you. If that doesn't teach you about life, nothing does. But it's vivid for me still. I've never told anyone."
