Immigration Act 1971

24 (1) An immigration officer or constable may arrest without warrant a person who has been released by virtue of paragraph 22 above—

(a) if he has reasonable grounds for believing that that person is likely to break the condition of his recognizance or bail bond that he will appear at the time and place required or to break any other condition of it, or has reasonable ground to suspect that that person is breaking or has broken any such other condition ; or

(b) if, a recognizance with sureties having been taken, he is notified in writing by any surety of the surety's belief that that person is likely to break the first-mentioned condition, and of the surety's wish for that reason to be relieved of his obligations as a surety ;

and paragraph 17(2) above shall apply for the arrest of a person under this paragraph as it applies for the arrest of a person under paragraph 17.

(2) A person arrested under this paragraph—

(a) if not required by a condition on which he was released to appear before an immigration officer within twenty-four hours after the time of his arrest, shall as soon as practicable be brought before an adjudicator or, if that is not practicable within those twenty-four hours, before a justice of the peace acting for the petty sessions area in which he is arrested or, in Scotland, the sheriff; and

(b) if required by such a condition to appear within those twenty-four hours before an immigration officer, shall be brought before that officer.

(3) An adjudicator, justice of the peace or sheriff before whom a person is brought by virtue of sub-paragraph (2)(a) above—

(a) if of the opinion that that person has broken or is likely to break any condition on which he was released, may either—

(i) direct that he be detained under the authority of the person by whom he was arrested; or

(ii) release him, on his original recognizance or on a new recognizance, with or without sureties, or, in Scotland, on his original bail or on new bail; and

(b) if not of that opinion, shall release him on his original recognizance or bail.
