An inquest jury has concluded that a teenager who collapsed whilst being restrained at Liverpool One shopping centre died from 'natural causes'.
Mzee Mohammed Daley was captured on camera and mobile phone footage carrying a knife and behaving erratically at the Liverpool One shopping centre.
He was being restrained by security staff and police when he collapsed and died.
The jury concluded that he died as a result of cardio respiratory arrest, due to suffering an acute psychotic episode and prolonged physical exertion.
Mzee's family had complained to The Independent Office for Police Conduct (IOPC) about the way he had been restrained by Merseyside Police.
The IOPC's Regional Director, Amanda Rowe, said: "Mzee’s family and friends have suffered greatly since his tragic death.
"I have seen the footage of Mzee on the day he passed away; it is difficult to watch, and I cannot comprehend how painful this must have been for his loved ones.
"On behalf of the IOPC I offer our sincere condolences for their loss.
“Today we published a detailed report which reflects our robust investigation; we looked very carefully at how and why Mzee was restrained.
"The evidence we gathered did not indicate that any officer committed a criminal offence or behaved in a manner that would justify the bringing of disciplinary proceedings.
"We concluded that the decision to restrain him was based on a number of risk factors and this complied with guidance, policy and training."
