Whalley Range death: Tributes to Kieran Crump Raiswell
Relatives have paid tribute to a "loving" and "caring" teenager who was stabbed to death in a daylight street attack in Manchester.
Kieran Crump Raiswell, 18, was attacked near a bus stop on Upper Chorlton Road, Whalley Range, on Wednesday afternoon.
Police believe he was stabbed by "a lone offender armed with a knife".
Ch Supt Jim Liggett said people had "an absolute responsibility to him, his family and to the justice process" to come forward with information.
In a statement his family said he was a "quiet, easy-going boy" with his "whole life ahead of him" and was "loved by all who knew him".
The Manchester City fan was on a gap year and was due to begin studying history at Sheffield Hallam University in September.
Police were called at around 14:20 GMT. Mr Crump Raiswell was treated by paramedics, who took him to hospital, but he later died.
A post-mortem examination has not yet taken place.
Police said they believe another teenager may have been responsible, but the reason for the attack remains unclear.
Mr Liggett said: "Officers are still very much in the early stages of this investigation and all we know for certain is that this young man has been attacked in broad daylight as he walked along the street.
"We are looking for one offender but the area would have been extremely busy.
"Undoubtedly, the answers to these questions may lie within the community and I would urge residents to stand side by side with us and help us bring this man's killer to justice."
