Calgary police are hoping to jog some memories about a string of bank robberies in the city.

Officers are now reviewing nine robberies that took place since August 2011 in hopes of finding new information.

Staff Sgt. Bruce Walker says taking a second look at so-called cold cases is important.

"The people unfortunately that are present at the time of these incidents — they can be emotionally traumatic — a lot of times they're scared and we just want to ensure them ... even though at this point we don't have the identity of the suspects involved that we are still actively investigating and trying to uncover any leads," he said. 

Police are now looking for seven individuals in connection to nine different holdups.

20 bank robberies in 2013

There have been 20 bank robberies in the city so far this year.

Often the culprit uses a note to get the money, but Walker says police are concerned about the growing number of criminals who also threaten tellers with a weapon.

"It is a concern for us, and anytime that people are victimized — especially in the banking industry — we take it very seriously and again we continue to investigate and seek out the identities of these individuals," said Walker.

Anyone with information regarding the robberies is asked to call the Calgary Police Service robbery unit at 403-428-8787 or Calgary Crime Stoppers.
