SINGAPORE - A woman who tried to climb down a storey at a Housing Board block in Sengkang to get into a man's flat on Sunday (Sept 3) was arrested in relation to a case of intentional alarm.

The incident occurred around 1.30pm at Block 336B, Anchorvale Crescent.

A neighbour spotted the girl on a ledge at the third-floor corridor, and took a video of it, Lianhe Wanbao reported on Monday.

The neighbour, Ms Yusliena Zulkifli Smith, told Wanbao that she had been airing her laundry when she saw a woman squatting on the ledge along the corridor.

She said the woman was looking at the kitchen window of a unit on the second floor, and seemed to want to climb inside.

"I screamed and asked her what she was doing," said Ms Yusliena. "She did not answer and instead placed her finger to her lips and asked me to keep quiet."

Ms Yusliena then rushed outside her home and went to the corridor to ask the woman what she was doing.

The woman climbed back into the corridor and left, Ms Yusliena said.

She then called the police. Ms Yusliena had posted a video of the incident on her Facebook page, but later took it down.

The police told The Straits Times on Monday that they were alerted to a case of intentional alarm at Block 336B, Anchorvale Crescent, on Sunday at 1.36pm.

"A 21-year-old woman was arrested in relation to the case," said the police spokesman.

ST understands that she had wanted to go to her ex-boyfriend's home, but he did not want her to, so she tried to climb down from the third floor to his home on the second floor.

Police investigations are ongoing.
