Original article (4:08 p.m. PDT) Police say there is not an ongoing public safety threat after one person was injured in an explosion at around 2:30 p.m. at McNary Field.

No details were available about the cause of the explosion, but according to Lieutenant Ben Harvey of the Corvallis Police Department, one person was taken to the hospital with serious injuries. Harvey anticipated the park and its adjacent parking lot would be closed for “about four hours,” and said that the CPD would give updates about the situation via social media.

Harvey added that CPD plans to give more details about the incident at around 5:00 p.m.

“We’re going to take our time to conduct the investigation and be careful,” Harvey said.

A crowd of onlookers gathered on the other side of the street, with some coming after hearing the sound.

“I was walking through the middle of the grass at the MU, and I heard it,” said Magnus Capellen, a third year Forestry major. “I was like … ‘that’s definitely more than a firework.’”
