A long-running feud involving thugs from 'Ackee Walk' and 'Common' is believed to be behind the shooting of four men, including political commentator and talk show host Mark Wignall, in two incidents in the St Andrew North Police Division yesterday morning.In the first incident, which occurred shortly after 7:00 am, men drove past the Molynes Road entrance to Ackee Walk and fired several shots at a group of people. One man was hit in the leg.
