Kennewick and Richland police are continuing to investigate a large explosion that rocked a south Kennewick neighborhood on Sunday.
People living the nearby neighborhood heard the loud explosion in the Southridge High School parking lot during the afternoon and called Kennewick police, said Kennewick Lt. Aaron Clem.
And people in the area said they spotted a silver Ford Focus driving off toward Ridgeline Drive after the noise.
When officers arrived they found pieces of an exploded stock pot scattered across the parking lot, police said.
The Richland Bomb Squad was called in to help Kennewick detectives investigate.
There were no reports of injuries or damage to the school, and it does not appear to be targeted at the school, Clem said.
Anyone with information about the explosion is asked to contact Kennewick police at 509-628-0333.
