 As of 31 October 2013, there were 209 people detained under the CLTPA, two-thirds for gang-related activity, a quarter for unlicensed moneylending, and the remainder for drug trafficking and other syndicated crimes.Any police officer may, without warrant, arrest and detain pending enquiries any person in respect of whom he has reason to believe there are grounds which would justify the person's detention.In the 1960 case of "Re Ong Yew Teck", the High Court held that since a police officer ordering an arrest is not required to disclose facts which he considers to be against the public interest to disclose, it is futile for a court to objectively decide whether there are grounds justifying detention.
