AMSTERDAM has turned orange in grief after the brutal murder of 17-year-old Lisa - allegedly at the hands of a migrant already facing charges of rape and assault claims.

The teen from Abcoude was cycling home last Wednesday from a night out in the capital when she rang police to say she was being followed.

Officers reportedly listened helplessly to her final moments as she was ambushed and fatally stabbed before the line went dead.

Patrols raced to the scene but arrived too late, finding Lisa’s lifeless body in a ditch near Holterbergweg around 4am.

Forensic experts reportedly found multiple stab wounds to her neck and body.

Lisa's devastated parents and relatives joined hundreds of villagers in Abcoude for a minute's silence at the town's annual festival week on Tuesday evening.
