A robber who attacked three people at knife point on three separate occasions at a cash point in Kings Norton has been jailed for seven years and four months.
36-year-old Craig Berrey threatened his victims with a knife before stealing money on three consecutive days at the beginning of April.
Berrey, from Northampton, was caught by police during the third robbery after he was spotted acting suspiciously by a member of the public.
Officers arrived as Berrey grabbed a man in his 60s in an attempt to take his money.
