This is the moment that Dutch police investigating the murder of a 17-year-old girl and sex attacks on two other women discover a large knife tossed into a river outside the asylum seeker hostel.
The teenager, named Lisa, was cycling to her home in the suburbs in the early hours after a night out in Amsterdam when she realised she was being followed and called the police.
But by the time officers arrived Lisa was found lying dead in a ditch after being stabbed in the neck.
They soon arrested a suspect - an illegal unregistered migrant in his early 20s who was seized by a SWAT Team at a hostel for asylum seekers.
And it was in the river that runs past the A&O Hostel in Amsterdam Zuidoost that a knife was today discovered having apparently been discarded in a river.
