JOHANNESBURG - While police have been praised for their work in forensic services, forensic scientist expert David Klatzow says crime scenes need to be handled with more care.

Klatzow says if the scenes are tampered with it becomes hard to solve crimes.

On Wednesday at a forensic conference in Pretoria police said the identification of South African citizen, Cameron Dalziel, who died in a foreign plane crash is one example of South Africa's rich forensic.

But Klatzow says there are too many other incidents of crime scenes that were tampered with.

"The journey starts at the crime scene and if it's damaged, there's a major problem in doing forensic work so evidence that is compromised at the crime scene will never be better than that."

Authorities have argued that forensics, through the work of finger prints and DNA identification, has solved numerous cases in the country.

The police said they are looking to establish more forensic centres across the country so cases can be dealt with more efficiently across all provinces.
