It only had an alcohol testing kit.He said he had raised the issue within his department before.He explained that he could not simply fill a vial with Novella's blood in the absence of a proper drug kit, because it would go against chain of evidence rules.Although Novella seemed to be behaving strangely, he did not refer him immediately for a psychiatric evaluation. He said it was up to a court to order a psychiatric evaluation.BreakdownThe facilities at Victoria Hospital did not have guards for a 72-hour observation, the court heard.However, the more Anders explained why he failed to follow instructions, the more answers Booth demanded.Eventually, the witness broke down.Saldanha adjourned to give Anders time to compose himself.Novella has pleaded not guilty to the murder and is expected to argue a case of diminished responsibility as a result of drug intoxication.An evaluation, by a panel of experts at Valkenberg psychiatric hospital, found that he was fit to stand trial.The trial continues on Monday.
