KITCHENER -- A bank in Cambridge has been robbed for the second time in just over a month.

Waterloo Regional Police were called to the Scotiabank branch on Saginaw Parkway and Franklin Boulevard just before 8 p.m. Thursday.

They say two men entered the bank and demanded money from the teller.

One of them was carrying a gun.

The men then took off in a black 4-door sedan with an undisclosed amount of cash.

Police say no one was injured.

One of the suspects is described as black, in his mid-20s with an average build. He was wearing a black puffy coat with fur around the hood, black pants, black Nike shoes and black gloves.

The other man is described as having brown skin, also in his mid-20s with an average build. He was wearing a grey hoodie, black pants, black gloves and a black hat.

Both had masks over their faces.

The same branch was also targeted by thieves on December 13.

In that incident three men entered the Scotiabank and left with an undisclosed amount of cash.

All three were described as being black, around 5’8 with medium builds and hoods over their faces.

Police say they’re investigating any possible link between the two robberies, as well as all other unsolved bank robberies across Waterloo Region.

Other businesses in the area say this latest incident is concerning and they want to see more security measures.

"They need outside cameras," says the owner of the Short Stop convenience store next door. "They've got to do something outside, they have to have some way to monitor traffic in and out."

The branch already has a security guard on site.

"They weren't letting people in unless they proved they belonged there," said one bank customer. "They made them take off their hats and hoods."

Scotiabank issued a statement to CTV News which says: "The safety and security of our employees and customers is our top priority. We continually review and invest in safety measures and training for our employees in our branches."

One customer says she has idea why this branch was chosen.

"Other banks, when you come in, they walk to an area where they get the cash and then bring it back. But here the money is accessible beside the teller. I think that's what's making them more of a target."

Police are asking witnesses to give them a call.

"We encourage anybody that noticed suspicious activity or individuals to contact police immediately," says Ashley Dietrich of  Waterloo Regional Police.

They're also looking for dash cam video from any vehicles that were in the area at the time of the robbery.
