Morrissey has claimed he was sexually assaulted by a member of staff at San Francisco International Airport earlier this week.

Posting on True To You, an online Morrissey fanzine, the singer detailed an incident where he was approached by an airport security officer who “crouched before me and groped my penis and testicles.”

"Luckily I was accompanied by two members of British Airways Special Services, who were horrified at the sexual attack and suggested that I lodge a complaint."

He said that he confronted the staff member and complained about the treatment only to be rebuffed by the man, who repeatedly said "That’s just your opinion."

“Since the penis and testicles were mine and no one else’s, then my opinion must surely have some meaning," he said.

"But, of course, what the airport security officer was saying was: your opinion will never count in the eyes of the law.”

He went on to say that though the incident was caught on CCTV, he doubted anyone would be reprimanded over what happened, and cast doubt over the airport’s duty of care regarding its passengers.
