Three masked men shattering the glass front door of a Family Dollar store, and then storming through with guns, was all caught on surveillance video.
Police released the video Thursday evening.
"We're very concerned. You can see in the video it was a very dangerous offense," said Sgt. John Solecki, Reading Police Dept.
The crime happened Tuesday night around 9:30, in the 300 block of N. 4th street in Reading, after the store had closed for the day.
Workers were still in the store taking care of deposits, employees said.
One of the men is believed to have used the end of his shotgun to shatter the glass in the front door, police said.
Another man was carrying a hand gun, investigators said.
The employees in the store at the time of the burglary hid inside a back office.
At one point the men knocked on that office door, but the employees never answered, investigators said.
Shortly after, the men took the cash from the safe and cash registers, and left right through same shattered door they came in through.
"It appears they were familiar with the business. They were probably in there before, and they cased the place before they went in. Just because of how fast they moved," Sgt. Solecki said.
Once captured the men involved in this crime will face burglary-related charges.
