A man in a long black trench coat and carrying what looked like a samurai sword forced a school into lockdown and sent armed police to the University of Waikato in Hamilton this morning.
Sixteen police were sent to the university to scour the grounds after reports of an armed man about 9.30am.
It took 90 minutes to track down the man.
He turned out to be a 25-year-old member of the university's sword fighting club, who was in fact carrying an umbrella that looked like a weapon.
"The sword is actually an umbrella that, when a button is pushed, activates,'' Senior Sergeant Rupert Friend said.
