She sat on the window frame of her seventh-storey flat, legs dangling.
A while later, she climbed out of her flat and stood on the narrow ledge outside her window, holding on to the grille.
For two tense, suspenseful hours, the long-haired woman, who was dressed in a red top and dark tights, kept police and rescuers at bay as they tried to coax her back into her flat.
The drama happened on Monday night at Block 634, Ang Mo Kio Avenue 6.
A resident in a facing block had alerted the police at about 8pm, Shin Min Daily News reported.
Upon arrival, police officers entered her flat and were seen speaking to the woman.
A neighbour on the sixth storey of Block 636, which faces the woman's block, said he had a direct view of the unfolding drama from his kitchen window.
The man, who wanted to be known only as Mr Tan, told The New Paper last night: "She looked very hesitant and anxious. She looked like she was gripping the kitchen grille very tightly.
"She also kept turning around and looking down as if she feared the height from where she was standing."
The 37-year-old sales manager said: "Whenever someone approached her at the window, she moved away.
"At one point, she moved to the far end of the ledge and wasn't holding on to anything at all. She only had her hands flat against the wall."
The scene attracted about 100 onlookers, including residents in the area, near the bottom of the block.
One resident, who was at a void deck, said a number of residents claimed the woman was on the ledge because she "wanted her husband to talk to her". It was unclear what may have happened between the two.
They said that her husband "thought she was just being dramatic when she first sat on the window frame".
Rescuers from the Singapore Civil Defence Force (SCDF), who arrived shortly, immediately got to work.
While an SCDF team prepared its equipment, other rescuers stationed themselves at the units directly above and below the flat from which the woman had climbed out from.
Meanwhile, an inflatable safety life air pack was deployed directly below where the woman was perched, as a safety precaution.
The drama ended at about 9.55pm when two Disaster Assistance and Rescue Team (Dart) personnel rappelled from the ninth storey and grabbed the woman.
They then lifted her back through the window into the flat to safety, to the loud applause of the onlookers.
A resident on the 11th storey at Block 636 said: "She screamed when the two rescuers got a hold of her after they climbed down the rope.
"I think she didn't hear them and probably got a shock when they suddenly grabbed her."
Police said they arrested a 46-year-old woman for attempted suicide. Investigations are ongoing.
