The incident took place around 8:50 a.m., Monday, July 22, when the Spring Valley Police Department received a call of a man on the campus spraying people with an unknown substance, said Officer Matthew Galli.
An investigation found that the unidentified man, entered the school, which leases the space to a day camp, and sprayed the nurse and another camp employee with the "chemical agent," said Galli.
Both employees were treated at a local hospital.
The school was placed on a brief lockdown that has since been lifted.
Police did not reveal if any arrests have been made.
