Packages delivered to two Canadian schools contained a human foot and hand which may belong to a Chinese student whose alleged killer was captured during a worldwide manhunt.
Deputy Police Chief Warren Lemcke said Vancouver Police were still investigating the two incidents.
He said: "There is no indication any student or staff has been targeted at any school.
"This must have been a very traumatic incident for all involved in the schools involved in opening the packages and the Vancouver Police Department will assist with any way we can with our victims services section."
