Mr Xu suggested to the police officer, who said her highest academic qualification for Chinese was N level, that there may have been a communication breakdown between her and Wu while she was translating the charge to her.
“I disagree. When I read out the charge to her, she said she understood it, and she acknowledged it,” said the officer.
Senior Staff Sgt Chang was the second police officer to be cross-examined by Mr Xu.
On July 1, the lawyer had asked the investigating officer, Assistant Superintendent of Police Francis Phua Tien Soon, if he was aware that the victim suffers from attention deficit hyperactivity disorder.
Deputy Public Prosecutor Matthew Choo interjected when Mr Xu made this claim. He said that there was no evidence the child has special needs and questioned the relevance.
Wu is accused of inflicting unnecessary physical pain and suffering to a two-year-old girl at a pre-school on May 11, 2022.
Among other things, she is alleged to have grabbed the girl by her shoulder and shaken her violently.
There is a gag order on the identity of victim and the location of the incident.
