Video footage from closed-circuit television cameras and cameras worn by police officers show that Madam Josephine Savarimuthu was not restrained by police at any point in time while in their custody.
The police said in a statement yesterday that they have invited the family of the 73-year-old woman to view the footage at their convenience.
They added that the video footage also showed that Madam Savarimuthu was alert, coherent and communicative when in police custody and did not appear to be distressed.
In a Straits Times Forum letter published on Wednesday, Madam Gertrude Simon wrote that her mother, Madam Savarimuthu, was handcuffed and had leg restraints on when she was moved between the police station, Changi Women's Prison and the court.
Madam Simon, 55, had, in an interview with The Straits Times, added that her mother - who lives alone - was also stressed and overwhelmed throughout the ordeal.
The authorities, in a statement on Wednesday, said that only in her transfer to the prison was Madam Savarimuthu restrained at the hands and legs - in line with standard Singapore Prison Service operating procedures.
Madam Savarimuthu was arrested after she lodged a police report at a neighbourhood police centre.
While processing her report, the police officer discovered that there was an outstanding warrant of arrest against her issued by the court last year for failing to attend court relating to a town council summons.
