Lyric discussion by losttango 

I used to go out with a woman who'd lived in Cambridge. She told me that her knickers had once been stolen by the guy who Arnold Layne was based on - which would suggest he was definitely a real person. She said it was pretty common knowledge in Cambridge that the song was about this guy.

@losttango I wonder how she knew who pinched her panties. Maybe he left a calling card.
