On 1 April 2003, SIR and the border control functions of CED were merged to form ICA in response to the 9/11 attacks and the Jemaah Islamiyah plots. The remaining functions of the CED was reorganised and renamed into Singapore Customs. ICA was to be part of the Home Team and a new, blue uniform was introduced to reflect that change. The first Commissioner of ICA was Lock Wai Han, who was in the Singapore Police Force before he oversaw the merger of the two agencies.
