That is how PDRM does it... They would frame you by planting evidence.

I was taught by pdrm to do the same to an individual that trespassed my mum's house. We didn't let him leave until cops came, then they took him to IPK Shah Alam sek7 there. While being processed the sergeant ask if anything lost at home. We said no, then he say if want to dakwa him must ensure plant some item from home in his pockets. Better to be valuables.

So what you said is possible that PDRM did to the kids.
