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, which also features Scots actor Martin Compston.

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, said 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. But she said: "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 more official. I said, 'Has there been a double booking?' The guy with my case said 'I don't know'. I said 'Who called you?' He said 'I don't know'. Then he let go of my case and walked off."

The next day Hawes told the show's police adviser, a high-ranking officer.

She said: "He put my mind at rest a bit. The police tracked the guy's number plate through CCTV."

Asked whether police worked out what happened, she said: "I don't know ... it was a bit frightening."
