Nine people ranging in age from 16 to 23 have been arrested in a series of recent "takeover-style" bank robberies in the Toronto area.

Police said the five robberies took place between July 22 and Aug. 13. Four of the robberies were in Toronto and one was in Markham.

The robberies followed a similar pattern: a group would enter the bank armed with guns and jump over the counters and quickly take control of the bank's employees and customers.

Police said the suspects used a combination of physical force and threats to get to the cash quickly.

The suspects also often switched roles, from lookout to getaway driver.

Of the nine people charged, four are youths. Police have also issued a warrant for one young person they believe was also involved in the robberies.
