A police officer may only arrest a youth in relation to an offence if the arresting officer believes the offence is serious enough to warrant an arrest and also believes, on reasonable grounds, that –

(a) the arrest is necessary to prevent a continuation or repetition of the offence or the commission of another offence that, if it were committed by the youth, would be sufficiently serious to warrant the youth being arrested in relation to the commission of that offence; or

(b) the arrest is necessary to facilitate the making of a police family violence order, within the meaning of the Family Violence Act 2004 , an application for a family violence order under that Act or an application for a restraint order under Part XA of the Justices Act 1959 ; or

(c) the arrest is necessary to prevent concealment, loss or destruction of evidence relating to the offence; or

(d) the youth is unlikely to appear before the Court in response to a complaint and summons.
