SINGAPORE - The authorised examiner investigating the Tah Ching lift accident has requested for one more week to carry out additional tests before submitting a final report.

The Building and Construction Authority (BCA) said on Sunday that it has acceded to this request. This means that the report, which was originally due on Monday (Oct 26), will now be ready only next month.

The BCA added: "A preliminary investigation report will be submitted to BCA tomorrow, 26 October (Monday). BCA will review the findings and will make an independent assessment within a week of receiving the final investigation report."

On Oct 9, Jurong resident Khoo Bee Hua, 85, had her left hand severed by a lift in Block 322 Tah Ching Road where she lives. The grassroots leader, who was trying to stop the lift doors from closing before her dog could enter the lift, also fell and broke her left leg during the accident.

She was transferred from National University Hospital to Jurong Community Hospital on Thursday (Oct 22), said her 59-year-old son, who only wanted to be known as Mr Lee.

Following the incident, the BCA asked Jurong Town Council, which oversees the maintenance of the lift, to appoint an authorised examiner to investigate the case.

Deputy Prime Minister Tharman Shanmugaratnam said on Sunday at the sidelines of a tree planting event that Madam Khoo is "recovering well".

When asked if the findings of the investigation report will be made public, Mr Tharman, who is also MP for Jurong GRC, said: "I should think so...There is nothing to be kept under wraps."
