On 12 August 2005, train services were disrupted for hours as Liu Tze Yuen created a bomb threat at the station which turns out to be false. He was also accused of putting boxes in public buses on 7 July and 12 August – the latter on the same day he was accused of carrying out the hoax at Hougang. Liu allegedly intended the passengers on the two buses and the train station to believe that the packages contained explosive devices; he was later sentenced to 3 years in jail.
