A hammer-wielding man was caught on camera smashing four cash machines in a revenge attack in Hubei province, north China. The man was reportedly seeking shelter at the bank from the rain earlier in the day but was chased out by a security guard who accused him of loitering. The man held a grudge against the guard and decided to take matters into his own hands. The 35-year-old man, later identified to be Cai, then headed to another nearby bank and vandalised two other ATM machines.
