Peter Sutcliffe, 74, was one of the UK's most notorious prisoners, having murdered at least 13 women across the north of England in the late 1970s.
His prison term had been increased to a whole life sentence in 2010 and he was being held at HMP Frankland in County Durham.
Sutcliffe had recently been diagnosed with COVID-19, but is understood to have refused further treatment when he was taken to a nearby hospital.
