The tragic death of "beautiful wee princess" Katie Bogle has left her family both here and in the US completely devastated.
It has emerged that the five-year-old had been playing on her scooter when she was hit by a car in Irvine Park, Bangor, on Thursday.
She was taken by ambulance to hospital following the collision around 5pm, but died from her injuries.
Katie's family had just moved to Bangor from Donaghadee weeks before the tragic accident.
Local reports say the grey coloured Hyundai car that collided with the little girl was driven by a female neighbour.
Friends and relatives of the Bogle family began to arrive at Irvine Crescent, where Katie lived, to lay bouquets of flowers as a mark of respect.
Emotions were running high in the quiet cul-de-sac yesterday as the realisation of what had happened sank in.
It is understood Katie's parents were unable to return to their home following the accident.
The driver is also reported to be highly distressed over the collision and the death of the little girl.
The two schools which she had attended issued moving statements about the child, who had made a huge impact on fellow pupils and her teachers in her short life.
Edwin Barr, the principal of Donaghadee Primary School, described Katie as a "beautiful, bubbly character who liked to take part in all school activities".
He said: "Pupils, staff, parents and governors of Donaghadee Primary School are all shocked and deeply saddened by the news of Katie's tragic accident.
"Katie showed a wonderful enthusiasm for learning. She was caring and thoughtful, looking out for classmates in the classroom and playground."
The school cancelled a planned fair last night as a mark of respect to the Bogle family.
The little girl started at Donaghadee Primary School last September before moving on to Kilmaine Primary in Bangor.
A statement from Kilmaine Primary School read: "We are sorry to learn of the tragic death of Katie.
"She was a delightful little girl who was well loved.
"We have not yet been able to come to terms with this shocking incident."
The Belfast Telegraph understands that Katie's mother Michele is a nurse at the Ulster Hospital in Dundonald.
Katie's aunt Heather Bogle, who lives in North Carolina, received many touching messages of support from various friends on her Facebook page after posting a picture of herself and Katie in happier times.
One poster called Katie a "beautiful wee princess", while another wrote: "She was such a special little girl and you, an amazing auntie."
Councillor Peter Martin described the incident as an "unthinkable tragedy".
"As a parent of two young children, it just rips the heart out of you to think that this could happen to any child," he added.
And Ards and North Down mayor Alan Graham said that his thoughts and prayers were with Katie's family at such a heartrending time
He added: "The loss of a child is one of the most tragic and painful situations imaginable."
Sergeant Brian Shankey of the PSNI appealed for information and asked anyone who was in the area of Irvine Park around 5pm to come forward and contact police in Bangor on 101.
