Authorities in Philadelphia say one of two suspects in an explosion at a Philadelphia ATM this week is in custody.

According to Fox News, the incident took place at around 9:30 p.m. on Wednesday at a cash machine inside a beer distributor near the intersection of Jasper Street and Allegheny Street.

“The business was open,” said Philadelphia Police Capt. Sekou Kinebrew. “People were in there. This could have been a catastrophic outcome.”

The explosion was caught on surveillance tape and appears to show a male suspect entered the business with an explosive device in his pocket. A female accomplice allegedly removed and lit the device before tossing it near the ATM.

The devices used in the explosion were described as “quarter sticks,” or crudely constructed and often very potent explosives.

“All you have to do is light the wick and wit and it will explode,” Kinebrew said.

As powerful as the explosion was, he said it should send a clear message to anyone else planning a similar crime.

“If the objective, and we believe it is, is to breach the compartment where the money is held, it doesn’t work,” he said. “So stop.”

Though the machine was significantly damaged in the explosion, the area containing cash was not opened.

Kinebew said of the plot that the “one thing it won’t result in is the perpetrator getting the money.”

The store’s owner told reporters that he recognized the female suspect as a repeat customer. The woman was reportedly arrested early Thursday morning.

Philadelphia police say Wednesday’s incident was the fourth explosion in the city this month.

“Our bomb squad is looking at that in tandem with these other ones,” Kinebrew said.
