PHILADELPHIA (CBS) — Philadelphia police are searching for armed suspects who illegally entered Sturgis Recreation Center in Oak Lane. Police released surveillance video of a group of people who allegedly broke into the center last Thursday before it opened.

According to police, a woman was able to get into the building around 11:30 a.m. Shortly after, several others showed up in a white minivan and dark-colored car.

Police believe they may have been shooting a music video but parents are still taken aback. They were seen inside and outside, holding semi-automatic rifles.

“I really don’t know what to say. Wow, that’s super scary,” parent Doris Valdez said. “I was told that there was spray paint outside the building but that’s about it.”

They left right around the time the recreational center was scheduled to open.

One parent who watched the video says her second grader will continue to attend the after-school program.

“She’s been going since kindergarten, so about three years. It’s pretty safe here, so this incident, I don’t know what happened. But everybody was pretty shaken up,” the parent said.

Police are looking for a 20-year-old black female with blonde highlights in her hair, and several black men who appear to be between 20 and 30 years old.

Police say it’s unclear if the semi-automatic weapons are real and that’s something police are hoping to get to the bottom of.

“They got cameras everywhere so that’s the good part,” one woman added.

If you have any information, you are asked to call police.
