Alachua County Sheriff's deputies believe most likely a group of burglars broke into the night deposit box late Sunday night or early Monday morning. Detectives are not staying how they did it so as not to encourage any copycats.

Security employees work to secure the night deposit box at the Bank of America on Newberry Road, west of I-75. The security tape says 'Do not cross,' but you better not deposit anything either.

The Mother Earth Market is one of several business customers in Newberry Square who lost a weekend deposit. The Market deposited about $1200 Sunday.

"I'm surprised that someone can get into the night deposit box," says manager Burt Polansky. "It makes me a little nervous about dropping off money in the future."

Bank of America employees made the discovery Monday morning. Nobody had checked the box since early Saturday afternoon. Bank employees say they have not had a burglary, a robbery, or even an attempted robbery in at least 15 years.

"It is a very difficult thing to investigate," says Lt. Steve Maynard with the Alachua County Sheriff's Office. "This is likely the work of a group that may travel around. They are here today, gone tomorrow-type thing."

Despite the security camera mirror near the box, there is no camera behind the glass so there is no surveillance video of the crime. But detectives will be looking at other businesses and cameras to see if they can get any clues.

Polansky says a bank manager told him the money is federally insured and will be replaced, but his Sunday deposits may be a thing of the past.

"I will probably call my boss and see if they don't want us to do that," says Polansky. "We might just want to keep it till Monday, if that does seem like a safe alternative."

Business customers should be able to show proof of their receipts and get their money replaced. Personal customers may be out of luck for any cash deposits, but should be able to stop any checks that were in the night deposit box.
