A young widow has tearfully demanded an inquiry into how a psychotic man was free to kill the father of her newborn baby days after knife and assault charges against him were dropped.
Dr Jeroen Ensink, 41, was ferociously stabbed to death by Nigerian student Femi Nandap as he left his flat in Islington, north London, in December last year. The victim had gone out to post cards announcing the birth of his daughter Fleur 10 days before. When the renowned academic failed to return, his wife, Nadja, went outside to find police had cordoned off the street and the cards her husband had been carrying strewn on the pavement spattered with blood.
Nandap, 23, from Woolwich, south London, appeared before the Old Bailey to be sentenced having admitted manslaughter by diminished responsibility. The court heard how he became psychotic from smoking cannabis and believed voices telling him he was a "Messiah" in Spring last year.
In May, he was arrested and charged for wielding a knife in public and punching and biting a police officer. While on conditional bail, Nandap went home to Nigeria where he was treated for mental illness. His sister informed British police about his condition in August and handed in a certificate saying he was unfit to travel.
On his return in October, Nandap had stopped taking anti-psychotic drugs. Then just six days before the killing, charges against him were dropped at a magistrates' court in December. The court was told the London School of Economics student should not even have been in the country when he killed Dr Ensink as his visa had lapsed.
Prosecutor Duncan Atkinson QC conceded the decision made days before the attack was "not as it should have been". He told the court there had been a review at the "highest level" and the issues involved monitoring on bail and identifying mental illness earlier.
Later, Mr Atkinson said the Home Office had confirmed that Nandap's three-year student visa was still active in December last year. The court heard he had been granted the visa in September 2014 for the course on Oriental and African studies and economic development.
