Nadine Chua<\/strong> To sabotage rival contractors, a man damaged and removed advertisements they put up at new Build-To-Order (BTO) estates in Toa Payoh and Ang Mo Kio.<\/p>\n On Sept 22, Lee Sai Koon, 75, was sentenced to 10 days\u2019 jail<\/a> after pleading guilty to three charges of mischief.<\/p>\n The court heard that the police became aware of his actions after residents living in Lorong 1 Toa Payoh<\/a> alerted them in August and September 2025 that advertisements stuck on their doors appeared to have been intentionally damaged.<\/p>\n Deputy Public Prosecutor Mark Chia said contractors competing for business at newly completed HDB blocks<\/a> would cover up the posters or cut them up with penknives to render their competitors\u2019 advertisements ineffective.<\/p>\n Lee, the sole proprietor of a firm called Tong Sheng Impex \u2013 which designs, manufactures and installs metal racks for storage purposes \u2013 was one of the contractors involved.<\/p>\n He committed the offences at Block 403A Lorong 1 Toa Payoh, part of the Toa Payoh Ridge BTO project, and Block 246A Ang Mo Kio Street 21, part of the Kebun Baru Edge project.<\/p>\n On June 29, 2025, Lee was at Ang Mo Kio Street 21 to put up posters to advertise his firm\u2019s services when he saw six posters put up by a competing company on the notice board in a lift lobby.<\/p>\n When he failed to open the notice board to remove the posters, he took a can of black spray paint from his vehicle and sprayed it over all the posters.<\/p>\n His actions were captured on CCTV.<\/p>\n Lee committed the offences at Block 403A Lorong 1 Toa Payoh and Block 246A Ang Mo Kio Street 21.<\/p>\n PHOTO: COURT DOCUMENTS<\/p>\n<\/figcaption><\/figure>\n<\/div>\n When Lee was told by the police that his actions were being investigated, he returned to the block in an attempt to clean the paint off but was unsuccessful.<\/p>\n On another occasion in August 2025, Lee and his wife removed the posters pasted inside the lifts at Lorong 1 Toa Payoh before putting up their own posters.<\/p>\n Lee then used a penknife to cut his own posters so they would come off in pieces, making them more difficult for his competitors to remove.<\/p>\n Lee was arrested in January, while his wife was given a conditional warning for her actions.<\/p>\n Those convicted of mischief can be jailed for up to two years, fined, or both.<\/p>\n Have something to say?
