Conn. Practice Book § 31a-13

(a) Upon written application in a delinquency

proceeding, a take into custody order may be

issued by the judicial authority:

(1) Upon a finding of probable cause to believe

that the child or youth is responsible for (A) a

delinquent act, including violation of court orders

of probation or the failure of the child or youth

charged with a delinquent act, duly notified, to

attend a pretrial, probation or evaluation appointment, or (B) for failure to comply with any duly

warned condition of a suspended order of detention. The judicial authority also must find at the

exists before issuing the order;

(2) For failure to appear in court in response to

a delinquency petition or summons served in hand

or to a direct notice previously provided in court.

(b) Any application for a take into custody order

must be supported by a sworn statement alleging

facts to substantiate probable cause, and where

applicable, a petition or information charging a

delinquent act.

(c) Any child or youth detained under a take

into custody order is subject to Sections 30-1A

through 30-11.
