Ex-pupil of British School in the Netherlands held over shooting threat
Student's post said he planned to 'shoot my Dutch teacher and as many students as I can'

Dutch police yesterday arrested a former pupil at a British school in the Netherlands in connection with a threat to go on a shooting spree that saw armed police deployed and schools closed.
Police in the university city of Leiden, just northeast of The Hague, confirmed that a person had been arrested after the threat to "shoot my Dutch teacher and as many students as I can" was posted online at the weekend.
"Someone was arrested in connection with the threat and we're continuing our investigations," said a police spokeswoman, declining to give a name.
The British School in the Netherlands said: "We have been informed that a former student … has been arrested in connection to threats made against a Dutch school in Leiden."
The school - in Voorschoten, between Leiden and The Hague - said the pupil was expelled in October 2011 "after incidents regarding his behaviour and has therefore not attended the school for over a year".
Authorities in Leiden decided late on Sunday night to close secondary schools to thousands of pupils after a tip-off by Swiss police following the threat.
