Susan Boyle's frantic plea for help panics passenger at Derry Airport

This not the first time the singer has created ruckus in public.

Scottish singer Susan Boyle created quite a buzz with her "Help Me!" screams in an airport lounge. The Britain's Got Talent star was spotted looking tensed at the Derry Airport in Northern Ireland.

According to a report in the Sunday People, the World Music Award winner was running through the airport while pleading for help. However, after sometime, Boyle was comforted by the airport staff.

One of Boyle's close friend revealed that she in stress after her scuffle with a relative. The female friend said: "Susan's trip wasn't what she had hoped it would be. She had travelled to Derry for a birthday celebration and had taken her brother with her but sadly the two of them had a disagreement."

"He decided to leave early on his own which was a problem for Susan, who is not used to travelling alone and felt very vulnerable and upset. She became quite ­distressed and in the end her assistant flew out from Glasgow to collect her and brought her home safely the next day," the source added.

"Susan is a lovely woman and an incredible talent but she was really let down by being left on her own. She's home now and is absolutely fine and as with most family squabbles it will all be resolved," the insider said.

This is not the first time that the singer has created ruckus in public. In 2010, Boyle was seen singing and dancing at the Heathrow Airport, and reportedly screamed "I've escaped, I've escaped". In a separate incident in 2012 Boyle shouted "I just want to go home" at a Burger King restaurant.

Previously, it was revealed that Boyle is a Asperger's Syndrome sufferer. A source told the Mirror: "Susan's fragile mental health is no secret. It's well documented she has Asperger's. One of the aspects of this is she is unable to deal with emotional situations as it causes upset and anxiety.

"All she wants is to have a close family and be happy. But with her condition Susan can be a bit over excited and overreact. It's nice to see that the police have decided not to take any further action. She doesn't deserve that."
