Calgary police have now charged a fourth person in connection with a high profile bank robbery in Mission in November and say the suspect worked at the institution at the time the robbery took place.

Police have charged Kenza Belakziz, 20, of Calgary with conspiracy to commit robbery with a firearm, and six counts of robbery using a firearm.

At about 5:00 p.m. on November 26, police were called to the Bank of Montreal in the 2300 block of 4 St. S.W. for reports of a robbery in progress.

Officers descended on the area and locked it down to ensure the public's safety and to make sure there were no suspects left in the bank.

Three male suspects, Lucas Wayne Windsor, 21, Saleem Obaid Nasery, 21, and Matthew Alexis Valdes, 23, were all arrested and have since been charged.

Belakziz is expected to appear in court on Tuesday.
