The evidence from the forensic experts from the Health Sciences Authority (“HSA”) favoured Hossain’s account as well. They found Gunasilan’s DNA on the inside of the cling wrap as well as on the rubber bands used to fasten the bundles of drugs. It was submitted by counsel on behalf of Gunasilan that the DNA evidence is unreliable, not because there is no evidence of DNA. There was DNA as the officers testified, but that the DNA might have been transferred by accident. It is possible that Gunasilan’s DNA could have been transferred from the towel, which was inside the haversack, onto the drug exhibits. The evidence from the HSA expert was that it would be unlikely if the exhibits were tightly wrapped, leaving little room for an accidental transfer of DNA. The exhibits seemed to me sufficiently well wrapped that an accidental transfer seems highly unlikely. Furthermore, there is no evidence of Hossain’s DNA on the drug exhibits. Finally, there was no credible explanation or evidence as to how Gunasilan’s DNA was found on the towel in the first place.
