The proceedings involving the two witnesses, both of whom are placed under the Witness Protection Act, began with the victim testifying at about 2.15pm.
Earlier, investigating officer V Simon, who was called to continue with his testimony today, told the court that he conducted a “polilight” inspection on eight suspected semen stains found on a mattress cover at the scene and then sent them to the chemistry department for analysis.
“The use of polilight is to differentiate biological fluid between semen, urine, blood and saliva on the mattress cover,” he said during cross-examination by lawyer Rajpal Singh.
Simon, of the Perak police contingent headquarters forensics division and the 14th prosecution witness, said he also sent two “swab sticks” to the chemistry department for analysis.
During re-examination by deputy public prosecutor Liyana Zawani Mohd Radzi, Simon said he did not do a polilight inspection on a mop that was taken from the scene as it had been cleaned.
Questioned further by Rajpal, Simon said he agreed with the lawyer that the forensics team went to the scene at about 12.10pm on July 9, 2019, about 38 hours after the alleged rape. The victim had lodged the report 22 hours after the alleged incident.
He also agreed with Rajpal that the forensic investigation was made specifically based on information given by the complainant who led the team to a room on the first floor of Yong’s house.
Yesterday, Simon told the court that eight suspected semen stains were found on the mattress cover at Yong’s house, as well as four strands of hair.
He said that among the items taken from the scene were a mop, a man’s grey underwear, clothing, a pair of blue shorts, a pink underwear and a blue bra.
Yong, 51, pleaded not guilty to a charge of raping his Indonesian maid at his residence in Meru Desa Park here between 8.15pm and 9.15pm on July 7, 2019.
The case was earlier mentioned in the sessions court, but on Dec 15, 2020, the Federal Court allowed the defence’s application to transfer the case to the High Court for trial.
The Tronoh assemblyman was first charged in the sessions court here on Aug 23, 2019 when he was Perak housing, local government, public transport, non-Muslim affairs and new villages committee chairman.
