Imie Harrison, her twin and two other children, all aged six, were playing near Wolverley Court Lock in Kidderminster when three of them ended up in the Staffordshire and Worcestershire Canal. One of the other children is understood to have jumped in to help after Imie and another youngster fell into the canal. West Mercia Police said Imie was in the water for 'some time' before she was rescued. The ambulance service said Imie was in cardiac arrest when she was rescued from the water in Springfield Park. Her brother ran half a mile back home to raise the alarm. It is believed the group were playing by themselves and clambering over the gates of the canal lock, which is near the local park. A police officer walks across Wolverley Court Bridge over the canal near where Imie fell into the water Eyewitnesses told how Imie's mother Lisa Harrison, 45, frantically rushed to the scene screaming: 'My angel, please not my angel'. Ally Scott, 46, from Kidderminster, said: "I saw this woman come from out of the crowds by the canal in a right state. 'As the helicopter left that's when this lady got really upset. She was absolutely hysterical and crying. She was screaming and screaming, shouting "My angel, please not my angel." I just saw police running and running and police cars kept turning up. After about half-an-hour the police helicopter went up. Spt Purcell said police will be working with partner agencies during the investigation, including 'Children Services at the local authority to support pupils from Imie's school in Kidderminster. Safer Neighbourhoods Team will also be visible in the area to help the community come to terms with this tragic incident. He added: 'It's a very very rural location, it's not one of our centres of activity around the canals. 'Little angel' Imie Harrison's family are said to be 'absolutely devastated' by her death 'It's a distance from the children's house and a play park but it is somewhere that is walkable. 'The message remains the same, make sure you know where you're children are and keep them away from water because it's dangerous.' Gail Quinton, Director of Children's Services for Worcestershire County Council said: 'We would like to express our deepest sympathy for family and friends following the tragic death last night of Imie Harrison. 'Worcestershire County Council's Children's Services are working very closely with the police to support the investigation and also the school to support pupils and staff at this very sad and difficult time.' Friends and family have paid tribute to Imie, who was described as a 'little angel'. Imie's grandmother Tracey Ridewood said the child was a 'little angel' Grandmother Tracey Ridewood paid a touching tribute to Imie on Facebook underneath a picture of an angel. She wrote: 'You have another little angel to take care of Donna, Imie tell her nanny loves her and give her lots of love and kisses.' Neighbour Sharon Wiltshire said: 'It's absolutely heartbreaking. Imie was a gorgeous little girl, I'd see her beautiful fair hair bobbing part my window all the time. She was always smiling and always happy. 'This is a tragedy - I can't even begin to imagine how her family must be feeling. It's every mother's worst nightmare. 'My son used to play with Imie's twin brother and all the kids who live on the street play really nicely together. We all let them play on the street, and all of us parents look out of them. I feel safe letting my kids play outside because I know all the mums are looking out for them. 'I have no idea why Imie and the others were down by the canal - it's not normally where they are allowed to go. They must have slipped away and gone wandering down the canal. This is a very tight knit community, and we are all in shock - no-one can believe what has happened. All the parents are absolutely devastated. I don't think any of our children will be playing out for a long time after this.' Another neighbour Jean Flanagan, 71, added: 'The little girl used to play outside with her friends a lot - we would see her playing with her twin brother. They were inseparable. 'It's an absolute tragedy what has happened. Kids go down there a lot, but there are no safety barriers. The whole community has been rocked. Her mum is inconsolable.
