A knifeman who has admitted stabbing a university lecturer to death outside his home had charges for carrying a weapon dropped just days before, it can be reported.

Timchang Nandap, 23, repeatedly knifed Dr Jeroen Ensink outside his north London home on December 29 last year.

Dr Ensink, a 41-year-old biologist who worked at the prestigious London School of Hygiene and Tropical Medicine, had only become a father 11 days before and was on his way to post cards to friends and family back home in the Netherlands telling them the good news when he was killed.
