Policemen beat up boy for no reason

I WOULD like to highlight a situation that happened last Monday afternoon along 9th Street, Top Town, Lae, between my son and the police.
My son has just completed Grade 12 at Coronation College.
On his way home after collecting his reference letter, he was called over by a group of policemen hanging around 9th Street.
They asked him in Tok Pisin yu bilong we and he replied Morobe.
They asked again wanem hap bilong Morobe, he replied Wau.
They said yu Morobe ah and two policemen, who looked liked highlanders, swung their fists at him.
They punched him over and over again until he fell and they kicked him three times on his ribs.
After beating him, they searched him and his bag.
They asked him what was in his bag, he replied paper bilong skul.
They got his bag and saw the school’s reference as he had said.
They then asked him what were in his pockets, he said he had nothing.
They went ahead and searched his pockets only to find nothing.
They then told him to take his trousers off in front of many on-lookers who had gathered.
He did not oblige and they swore at him using the K-word.
He took his trousers and shoes off and was left standing in his sportswear.
They told him to put his trousers on his head, which he did and carried his shoes in his hand.
They continued to harass him by asking if he wanted to walk home naked, he replied bos nogat.
They then told said to him to say “tenk yu bos” (for mistreating him) which he did and they let him go home.
He noted that the policemen were from Port Moresby as indicated on their uniforms.
We lodged a harassment complaint to Lae metropolitan commander Nema Mondia afterwards.
But Mondia told us that there was a “state of emergency” and that my son was held for disturbing traffic, which was not true at all.
We are not aware of a “state of emergency” being declared in Lae on Monday, Nov 7.
Why was my son assaulted by the police when he did nothing wrong?
This is an example of an innocent boy who got beaten up by the police simply because he is from Morobe.
The policemen had overstepped the line.
For one, they should not have sworn while in official uniform.
Where is their neutrality as law enforcers?
Did you come here to Lae to solve this current crisis or create a new one?
