A traffic warden faces the sack after his foul-mouthed rant at a motorcyclist was caught on video.
The Westminster council parking attendant is seen shouting at Warren Djangoly and making obscene comments about his wife during a confrontation in the West End.
Mr Djangoly, a management consulant from Barnes, said the abuse was “totally unprovoked”.
The warden, who has not been named, has been suspended after a video of the abuse, filmed by another biker, was posted on YouTube.
The recording shows the warden appearing agitated at being photographed, and saying: “Don’t be taking my picture,” before he snaps at Mr Djangoly: “Go and give that to your wife because I’ll be f***ing her soon.”
He repeats the comment as he turns his back and walks away.
Mr Djangoly, 46, said it was effectively a “threat of rape”, which he said was particularly alarming as private parking contractors have access to the DVLA database, including motorists’ home addresses.
He told the Standard: “I was shocked when he swore at me but I didn’t realise exactly what he said until I saw the video. It’s really quite appalling. It was also totally unprovoked.
“I only said to him not to bother giving me a ticket because I was going, and he got all aggressive, saying don’t tell me what to do’.
“What came out of his mouth next was astonishing and absolutely outrageous. It’s very concerning when someone says that to you, and it was really quite traumatising because there’s the worry that these people have access to our records.”
He said he has spoken to the police about the incident in New Cavendish Street this month, but is not sure whether to make a formal complaint.
He is also demanding a full apology from Westminster council and its parking enforcement contractor NSL Services, which employs the warden.
Dr Leith Penny, Westminster’s strategic director of city management, said: “Our parking attendants do a difficult and challenging job. However, Westminster council demands the highest standards from its parking staff and we do not tolerate this kind of behaviour which is clearly unacceptable.”
NSL spokesman Tim Cowen said the warden’s language was “shocking” and an investigation had been launched.
He added: “The civil enforcement officer in question has been removed from the Westminster operation and suspended while that investigation takes place.
“Behaviour like this is not acceptable and would usually result in dismissal if the case is proven.”
