Two of the three teen boys accused in a violent bank robbery in Markham, have now been charged in a similar incident in Pickering.

Durham police say the 15- and 16-year-old boys allegedly pistol whipped two bank employees and injured a third during the robbery Feb. 14.

They say three people were treated in hospital for injuries to their faces.

The teens face charges that include robbery with a firearm and three counts of assault causing bodily harm.

Police say the same boys, along with a 13-year-old, were also charged by York Region police after a robbery Wednesday night at an RBC branch north of Toronto.

Officers have said in that case, two bank employees were stabbed and two others were kicked in the face before officers arrived.
