[West Yorkshire Police has launched
an investigation - with officers
"providing reassurance and safety
advice to affected schools".
In messages to parents, one primary
headteacher said police had been
treating the threat as "credible" - and children
were being kept indoors for the whole day,
with gates locked and windows
and doors closed.
In its statement, the force said:
"Police are aware of an email which has
been sent to a number of schools in
West Yorkshire today."]
