SINGAPORE - At 8.22pm on May 23, a woman steps into Lift E at Block 1E in The Pinnacle@Duxton. She is alone.
She squats down. When she gets up, there is a pool of urine of the floor.
This indiscretion was captured by the closed-circuit television camera in the lift. Residents were appalled.
It professional Dennis Kwan, 40, said: "I was surprised and shocked. I have been living here for four years and this is the first time this has happened.
"The fact that it is an adult is even more astonishing. I would have expected the culprit to be a pet or a child.
"Those of us living on the higher floors had to hold our breath all the way down."
Dr Irene Sim, a 32-year-old dentist whose husband came across the pool of urine, said: "I thought it was from a pet.
"Pinnacle is a nice estate and this shouldn't happen here. The lift was sticky and the stench persisted."
Financial services consultant Clara Tan, 25, said her extended family was complaining about the stench, which lasted about a week. "There are public toilets in the nearby coffee shops. There must be something wrong with her - a mature adult - to do this. I avoided that particular lift after that."
The Tanjong Pagar Town Council later put up posters with caught two screengrabs of the CCTV footage. They showed the woman from the back.
Mentioning how the incident had "caused much inconvenience to the residents", the posters, which are in English and Chinese, "encourage all residents to take ownership of the common property".
The town council's public relations manager Shirley Aloysius said the Lift Surveillance System (LSS) was in place to deter crime and anti-social behaviour.
The aim of the posters was to seek help identifying the culprit as well as to deter such cases, she added.
Although the culprit has not been caught, the urination in the lift has stopped since the posters were put up.
Such images may be sent as evidence to the National Environmental Agency for prosecution, The Straits Times reported last year.
Those caught urinating in public places can be fined up to $150 under the Environmental Public Health Act. Recalcitrant offenders may be charged in court.
