A man has been arrested after a teenage girl was found murdered in a frenzied attack at a house in Teesside.
Police were called to a house in Troutpool Close on Hartlepool's Central Estate shortly before midday on Friday.
They found the body of 16-year-old Kim Bage who had suffered multiple stab wounds in the attack.
Cleveland Police said on Saturday that they had seized a 29-year-old man from Hartlepool for questioning in connection with the incident.
Forensic tests are continuing in the area but no weapons have been recovered.
'Fought valiantly'
Det Supt Tony Hutchinson, leading the inquiry, said: "The victim suffered a frenzied attack that would have lasted some minutes.
"The young girl I believe has fought valiantly for her life. Tragically, she was unsuccessful."
There was no sign of a break-in at the house, which belongs to a family member, although Mr Hutchinson said it was unclear whether the teenager lived there.
