Shocked witnesses have relived the horror as a seven-year-old girl was stabbed to death while playing in the park with her parents this afternoon.
A 30-year-old woman was arrested after brave member of the public overpowered and detained her as police locked down the 22-acre park.
The police have confirmed the woman "has some history of mental health issues". The young family were enjoying the spring sun when their little girl became a victim of a random attack.
Emergency services were called to park on Sunday afternoon and an Air Ambulance helicopter also attended the scene - she later died from her injuries.
