Man shot dead in Penang : GEORGE TOWN: A 29-year-old man was shot dead at close range by a gunman at Jalan Permai, Taman Brown here. The man was pronounced dead at a private hospital during the 10.50pm incident Saturday. He was chatting outside a friend's house before the gunman with his accomplices in two cars came and fired a shot at him. Police have since come out with a photofit of the suspect based on the friends description.
This is happening frequently in Penang especially on the island. Talk is that the underground societies have penetrated the island's booming construction industry. Labour supply and 'protection' for construction sites are under the influence of the underworld.
Plus the underworld is also active in their traditional businesses - prostitution, entertainment centres, drugs and money lending. And there is a money route.
Developers pay contractors. Contractors have to pay the underworld. Entertainment centre operators need licenses.
When there are gangs and money involved, there will certainly be turf wars and that is why we read about stories like this - where a 29 year old man gets shot and killed. There will be more such occurences.
