"Police investigation into this matter is near completion," police said.
They are remindng the public that though the investigation may be nearing completion the matter is still an ongoing investigation and the defendants are innocent until proven guilty by the courts.
"Due to the sensitivity of the judicial processes and the independence of criminal investigation, we urge for the public support by refraining from spreading assumptions and opinions that may interfere and compromise the ongoing investigation."
Police said they were fully committed to protect our community from the negative impact of illicit drugs.
"We urge anyone with information related to the case and illicit drugs to come forward and report it to the police but not on social media as it does not help."
