Mr Muhammad Zahier told CNA before a court session on Saturday morning that his team had spoken to all seven who were nabbed. During the interview, the woman informed him of her nationality.
“She told me that she was Singaporean and that she was 65 years old,” said Mr Muhammad Zahier.
“But we could not verify this as she did not have an identity card on hand. I then informed the court that we could not represent her because YBGK is a non-profit which only represents Malaysian citizens,” he added.
Mr Muhammad Zahier then added that his team represented the other six while the woman was unrepresented in court on Saturday.
He also told CNA that all seven individuals, including the woman, have been ordered to be remanded for seven more days.
Mr Muhammad Zahier said that the remand order was issued by magistrate Hidayatul Syuhada Shamsudin and was done to assist investigations under Section 302 of the Penal Code for murder.
CNA is not publishing the names of those who were arrested as they have not been charged.
CNA has sent queries to Singapore authorities regarding the nationality of the 65-year-old woman and if they are working with their Malaysian counterparts on investigations.
