The former The Smiths frontman was preparing to fly from San Francisco International Airport in California to London's Heathrow Airport on Monday (30Jul15) when the incident occurred.

He claims a male worker approached him at a security check and grabbed his privates as he gathered his belongings from an X-ray conveyor belt.

Morrissey also alleges two British Airways staff who were accompanying him through the airport witnessed the 'assault' and advised him to make a formal complaint with bosses at the travel hub.

In a statement, the singer writes, "On leaving the US on 27 July I flew from San Francisco International Airport to London on flight BA 284. At 2:30 in the afternoon I went through the usual airport security procedure including the stand-up 'scanner', and all was well - no bleeps and nothing unusual.

"Before I could gather my belongings from the usual array of trays I was approached by an 'airport security officer' who stopped me, crouched before me and groped my penis and testicles. He quickly moved away as an older 'airport security officer' approached.

"The officer who sexually assaulted me was identified... 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... The British Airways Special Services employees assured me that a complaint was worthwhile, and so I filed the appropriate information. However, before doing so, the guilty 'officer' was confronted... Apart from 'that's just your opinion', he would not comment, even though, since the penis and testicles were mine and no one else's, then my opinion must surely have some meaning...

"In the interests of imperishable bureaucracy my submitted complaint against this 'officer' will obviously be either unread or ignored because, as we all know, on matters of officialism it is not possible to be pleasantly surprised by anything at all."
