On Nov 5, the police received two reports of vandalism with writings purportedly linked to the 'Anonymous' group.
In the first case, spray-painted wordings were discovered on the wall and pavement of a building along Prinsep Link.
In the second case, writings in marker ink were discovered on the notice board of a HDB block in Tampines and a nearby bus stop. On 6 November 2013, a third incident was reported to the Police where spray-painted wordings were found on the walls of a HDB void deck in Woodlands.
Through investigative probes and extensive interviews, the police established the identities of the five suspects involved in the first case on Nov 5 at Prinsep Link.
On Nov 7, four of the suspects, Singaporean men aged between 21 and 26, were arrested. The remaining suspect, a 24-year-old Singaporean man, was arrested on Nov 8.
