The family of an 11-year-old girl fatally stabbed in a house say they are "utterly devastated" after the death of the "shining star".
Jasmine Forrester was attacked at a property in Kent Road, Wolverhampton on Friday and died later in hospital.
Officers were called shortly before 1am after a neighbour heard a disturbance and found the girl with multiple injuries, including one to the head.
Jasmine's father Simeon Forrester said: "This is a hugely tragic time for our family and the loss we feel is unexplainable. We are utterly devastated.
"Jasmine was a shining star and a huge part of us. We would really like to be left alone at this time while we come to terms with what has happened."
A 51-year-old man, who is related to the girl, has been arrested on suspicion of murder. He is in hospital receiving treatment for a cut hand.
A woman in her 80s suffered a suspected dislocated shoulder during the incident.
Superintendent Harvi Khatkar said: "This is an extremely distressing incident and our sympathies go out to everyone affected.
"We are working to establish exactly what has happened, and fully understand the impact that this will have on the community.
"But we do believe this is an isolated incident, and we are not looking for anyone else.
"Extra officers will be out patrolling the area to offer reassurance to residents."
The house has been cordoned off to allow forensic experts to conduct an examination.
A post-mortem examination is expected to take place on Sunday.
West Midlands Police are not looking for anyone else in connection with the incident.
