Beer bottles, flower pots, scissors and even a bicycle.
These are the items that Ms Tan Hai Li, a resident of Block 1 Eunos Crescent, said have been thrown from her block since she moved there less than two years ago.
Last Friday, a brick hurled from the block hit a man on his arm and the police were called in, said the 28-year-old housewife.
Police confirmed that they received a call for assistance at 1.39pm last Friday at the block, and said an injured man was taken to Changi General Hospital.
Investigations are ongoing.
Ms Tan submitted photos of Friday's incident - which showed bricks strewn on the grass patches and pavement in front of the block - to citizen journalism website Stomp.
A day earlier, she said a brick nearly landed on a couple and their three children who were walking there around noon. The impact of the brick caused some tree branches to snap, she added.
"This is getting ridiculous. What if children are playing downstairs and they get hit?" she told The Straits Times.
A few months back, she had called the police when she and her two children, aged one and two, were nearly struck by a large cardboard roll.
"Now, before I walk on the pavement, I will look out for falling items first," Ms Tan said.
She added that all types of items are thrown down every day, and residents now choose to walk in the void deck areas and avoid the pavement.
There were also high-rise littering incidents happening elsewhere recently.
Last month, a tin of white paint landed on a car parked in Yishun Street 11.
In October, MPs Tin Pei Ling and Baey Yam Keng, of Marine Parade and Tampines GRCs respectively, picked up a used sanitary pad and soiled diapers at the foot of blocks in their wards. They went to several homes in an attempt to hunt down the culprits.
From August last year to Dec 4 this year, 73 people were caught on camera throwing litter out of high-rise blocks, according to the National Environment Agency.
First-time offenders can be fined up to $1,000 and be made to do corrective work for up to 12 hours. Those convicted of throwing killer litter may be fined up to $2,500, jailed for up to six months, or both.
