Former state premier Dennis Napthine believes that if there has been any criminality involved in the cobalt crisis that has rocked the Australian racing industry, police must be involved.

Napthine, also a former racing minister, said he had followed the cases involving four leading Victorian horse trainers who are currently facing possible charges of cobalt irregularities, and said he was greatly concerned.
