 However, the Constitution specifically provides that no law inconsistent with those provisions which was in force before the commencement of the Constitution and which authorizes the arrest and detention of any person in the interests of public safety, peace and good order is invalidated by these Articles.No illegality in the detention by the police renders a detention order made subsequently by the Minister unlawful.When a detention order has been made against a person, any police officer may, without warrant, arrest that person and is required to forthwith report the arrest to the Commissioner of Police.
