Synopsis As Introduced Amends the Juvenile Court Act of 1987. Provides that any minor 15 years of age or older arrested or taken into custody under the Act for aggravated vehicular hijacking shall be detained in an authorized detention facility until a detention or shelter care hearing is held to determine if there is probable cause to believe that the minor is a delinquent minor and: (1) secure custody is a matter of immediate and urgent necessity for the protection of the minor or of the person or property of another; (2) the minor is likely to flee the jurisdiction of the court; or (3) the minor was taken into custody under a warrant. Provides that if the court makes that determination, the minor shall continue to be held until the disposition of an adjudicatory hearing under the Delinquent Minors Article of the Act.
