Terre Haute police say two 'suspicious devices' found in Collett Park Tuesday afternoon are unsophisticated explosives.
ISP's Explosive Ordinance Disposal Team was called to the scene around 9 a.m., after the Terre Haute Police Department says a park worker discovered a device while cleaning the park. A Terre Haute police officer came across a second device while searching the park.
Nearby Ouabache Elementary School was placed on lock down as a precaution.
Members of the ISP team dismantled the devices and turned them over to the Terre Haute Police Department for a criminal investigation.
Police used K-9 units to search the area for additional threats, but found none. They haven't made any arrests in the case.
