Contractor jailed for defacing rivals' ads at HDB estates

A contractor in Singapore was sentenced to 10 days' imprisonment on Tuesday for spray-painting over advertisements belonging to rival contractors at new Build-to-Order estates in Toa Payoh and Ang Mo Kio. The defacement of marketing materials was found to be part of an ongoing competitive dispute between contractors seeking to secure business at the HDB developments. Investigations revealed that multiple contractors had engaged in tit-for-tat sabotage of each other's promotional materials displayed at the estates. The practice involved deliberately obscuring or vandalizing advertisements, undermining rivals' visibility and marketing efforts in what appeared to be an escalating cycle of commercial rivalry. Authorities have heightened scrutiny of contractor conduct at new HDB estates, with the conviction serving as a warning against such unlawful competitive practices. The case highlights tensions within the building and construction sector as contractors compete for prominence in residential property marketing.
