SINGAPORE - A 71-year-old man has been arrested for suspected involvement in a series of vandalism acts that were discovered around the Clarke Quay area last week.

The police were first alerted to the graffiti after a report was lodged around 8am on May 23 about the defacing of a bus stop advertisement board along Hill Street. Following that report, officers conducted checks along Clemenceau Ave, River Valley Road, Hill Street and Victoria Street and found 11 other bus stops affected with similar graffiti.

In addition, the electrical box at the junction of Hill Street and North Boat Quay, and stone seats along Stamford Road were also affected. Phrases such as "We support CPF blogger" and "Return our CPF money" were scrawled in black block letters across the affected areas. These appeared to be messages of support for blogger Roy Ngerng, who on May 18 received a letter of demand from Prime Minister Lee Hsien Loong regarding defamatory remarks made in a blog about the Central Provident Fund scheme.

Police operations led to the arrest of the suspect on May 27. If convicted, he could face imprisonment of up to three years, or a fine up to S$2,000. Investigations are ongoing.
