Elsewhere, police in Wewak, East Sepik province, and Mt. Hagen in Western Highlands were patrolling the streets to prevent any rioting against Chinese traders.
In Port Moresby last Friday, acting Prime Minister Puka Temu instructed police to immediately investigate the incidents and deal with the ring leaders
He also instructed the Department of Commerce and Industry to investigate claims that a number of the Chinese shops hit were operating illegally.
Four Chinese-owned shops in Goroka were emptied of goods and an undisclosed amount of cash in a nasty Sunday reveille when men, women and children ran riot at 6.30 a.m.
At the gateway to the Eastern Highlands, Kainantu, the atmosphere was palpable but nothing happened as police kept a close tab.
In Madang on Saturday, however, in another morning raid, three shops were attacked by hordes of people believed to be squatters, at 7:30 a.m. Looters cleaned out one while three were left just as badly damaged when police arrived.
The incidents, like Lae where rioters came from Saw Dust, Kamkumung, West Taraka, 1 to 12 Miles settlements, were attributed to people from the sprawling squatter settlements of Parara, Pis Wara, and Genoka in Goroka and Sisiak 3 and Bukbuk settlements in Madang.
The Sisiak and Bukbuk settlers were joined by hundreds of other settlers in a force numbering hundreds to attack two new Chinese shops and a kai bar in the heart of Madang town. Other shops, Asian and national, were forced to close doors.
According to Eastern Highlands provincial police commander Augustine Wampe, women, children and men, numbering in the thousands, flocked onto the streets and prevented traffic flow.
Police and private security guards were also outnumbered.
Wampe said the people walked into four Asian shops and completely emptied them of deep freezers, radios, TV screens, washing machines and groceries.
The looted shops, which estimated their losses at 250,000 kina, or $92,000, were PMK restaurant and retail, Kim Restaurant, Saveu retail and wholesale and the Goroka Yacht Club. Others that were damaged included Hot Spot, Bintangor, SP Brewery and Trukai Industries.
In Madang, provincial police commander Anthony Wagambie said police apprehended 15 youths.
He said settlement youths took cue of the Lae and Port Moresby incidents last week and mobilized and entered J&Z Trading as it opened for business at 7.30 a.m.
Last Friday, Wagambie said he warned all shop owners in town not to open before 8 o’clock on Saturday morning to give time for police to prepare.
So as soon the doors were opened and the youths rushed in and emptied the shop, a routine patrol police responded immediately, he said.
A back-up police Mobile Squad arrived and dispersed the crowd and apprehended 15 suspects. The looters ran into the market and took refuge among the crowd, stopping police from shooting.
