Two months after seemingly unexplained explosions started being reported in the northern part of Phoenix, a new blast was reported over the weekend, renewing residents' concerns someone will eventually get hurt.

The latest blast took place around 5 a.m. on Saturday at a neighborhood in Glendale, located several miles south of the previous explosions -- and captured on a surveillance camera.

"It shook the walls. The window was shaking. It was intense and powerful," a woman, who did not want to be identified, told FOX10. The woman said she's shot different types of weapons and the sound she heard was not gunfire.

"It was definitely not a gunshot by any means, and after I saw the camera and I saw the explosion, it has to be something. Some kind of explosive," the woman told FOX10.

Phoenix police have not linked the latest blast to others, but 911 dispatchers have received over 100 calls from people reporting explosions since October 1 on the northwest side of the city and neighboring Glendale.

In each instance, residents reported similar experiences: a loud boom, a flash of light, but no damage or clear trace of what blew up.

Last week, Phoenix Police released a photo of a white pick-up truck that is being called a "vehicle of interest." The vehicle is described as an older model white Chevy or GMC pick-up truck with a possible black bed liner.

But officials have admitted there is "limited information" as to the source of the blasts, and no suspects have been identified.

Some of the residents near the blast on Saturday said they've been hearing the booms about twice a week since October.

“Somebody’s definitely gonna get hurt eventually on one of these,” Glendale resident Gina Bratt told TV3/CBS 5. “Somebody’s gonna be in the wrong place at the wrong time.”
