Keeley Hawes in taxi-driver mystery
Actress Keeley Hawes has told of a "frightening" incident which took place on her way to the Belfast set of BBC drama Line Of Duty.
The Ashes To Ashes actress stars as Detective Inspector Lindsay Denton in the police drama.
But she said that she had to ask a real, high-ranking officer to look into what had happened after she flew into Belfast Airport last July.
Hawes , 37, told the Radio Times that when she entered the airport arrivals lounge she found a minicab driver carrying a white board with her name on it.
The man took her suitcase and began to lead her to his car and "I went happily along with him", Hawes said.
But she told the magazine: "We'd just walked through the sliding doors out of the airport when I looked over and saw a bunch of drivers from a big cab firm and there was another sign with my name on.
"The second one looked slightly more official. I said, 'Has there been a double booking?' The guy with my case said 'I don't know'. I said 'Well, who called you?'. He said 'I don't know'.
"Then he let go of my case and walked off."
Hawes, who is married to her former Spooks co-star Matthew Macfadyen, said: "I should have noticed something when I said hello and he said 'Oh, I was hoping you'd be blonde'.
"That's not something people normally say - I guess it's a bit creepy."
The next day Hawes told the BBC2 show's police adviser, an anonymous high-ranking officer.
She said: "He looked into it and put my mind at rest a bit.
"The police tracked the guy's numberplate through CCTV. So (the adviser) is a good guy to know, on and off set..."
Asked whether police had ever worked out what the incident was about, she said: "I don't know... it was a bit frightening."
Hawes said that she enjoyed having a dowdy rather than glamorous appearance in her latest on-screen role as the single and lonely DI Denton.
"I've had a nice run in my career playing well-dressed and well-presented ladies and it's sometimes a stretch for people to imagine me playing anything else - although I have no qualms at all," she said.
"It was oddly relaxing and liberating to wander round on set in an elasticated prison outfit. I'd roll up to hair and make-up and make the tea - because I had nothing to do.
"Sometimes they'd put a bit of dark under my eyes or a bit more grease on my hair, but that was it."
The Upstairs, Downstairs actress added: "One of the sound guys watching said, 'It's almost like when Charlize Theron did Monster.'
"I thought 'Wow, well thank you.... I'll take that actually'. But then I remembered - Charlize Theron put on about three stone, had prosthetics and shaved off half her eyebrows but I was just me with no make-up."
A BBC spokeswoman later said Hawes had been concerned about the incident but it had since been discovered that her taxi was double booked.
She said: "Initially there were concerns but it has since come to light that there was a double booking on the taxi."
