Waikato police are refusing to comment on why they cordoned off a rural school the morning after a quiz night.
Hamilton CIB Detective Sergeant Andre Kavanagh said they would not comment on what happened at Ohaupo School overnight Friday as they were yet to determine if an offence had been committed.
Locals awoke to a portion of the school playground taped off on Saturday morning.
"Clearly we are looking into something that happened over the weekend but we are yet to determine whether there has been an offence committed," Mr Kavanagh says.
And, unusually, police aren't commenting about what may have happened.
