'They’re coming to get me': troubled student who killed an academic

Inquest highlights missed chances to identify decline in Femi Nandap's mental health

Jeroen Ensink's widow, Nadja Ensink-Teich, had one key question for his inquest: how could his killer be armed with a knife and at liberty on the day he stabbed the public health academic.

Seven months earlier Timchang "Femi" Nandap, a Nigerian student then aged 23, had been arrested after witnesses saw him brandishing a kitchen knife and acting strangely in the street where his sister lived. He began shadow boxing with a stranger, walked up and down the road, sat on the steps of his sister's flat toying with the blade, then shinned up a drainpipe and entered a first floor window.
