The incident took place at about 4.45pm, in front of a maid agency in the vicinity.
It’s believed that the maid was very distressed that she was going to be sent home.
It took police officers about 30 minutes to coax her down from the lorry and detain her.
One passerby said:
“I don’t understand what in the world she was screaming about, but she looked very sad and desperate. Hope everything is alright.”
