obligations, and of the prohibitions and internal rules (coveringgeneral conditions and separation of inmates), visiting rights, disciplinary measures, vocational technical training, medical services and security measures, among others. 300.Additionally, as part of an ongoing outreach programme, these rights were set out in information leaflets to be placed in the agencies of the Prosecution Service no later than three days after receipt, with instructions to ensure appropriate visibility for the information and consider how it should be stored without deterioration. 301.Under decision number A/011/2008 of the Attorney-General for the Federal District, guidelines were laid down for the conduct of the Prosecution Service regarding information to be set down in the summonses served on persons who appear to testify at a preliminary inquiry, and changing the capacity in which they were summoned. Detainees are also informed of their right to lodge complaints with the Department of Human Rights. 302.Finally, as a measure to ensure that persons undergoing any public prosecution investigation are summoned by the public prosecutor to assist with enquiries, on 14 May 2009 the Attorney-General for the Federal District issued official circular OC/002/2009, addressed to all offices of assistant attorneys-general, public prosecution offices and agencies of the Prosecution Service, judicial police headquarters and officers, laying down the formalities to be observed when preparing orders to locate and hand over such people. 303.Such orders are to indicate the date and time of handover of the person, their legal status, the offence or offences being investigated, and the grounds and reasons justifying the authorities’ action. 304.When conducting the preliminary investigation, public prosecutors may issue orders to locate and hand someone over in the following circumstances: (a)Accused persons: When after twice being summoned to appear and give a statement, they fail to do so; When the steps taken prove ineffective in obtaining the data for summoning the accused; When the accused appears before the public prosecutor and reserves the right to testify on a specified later date and does not appear for that purpose, and When the circumstances and nature of the crime so dictate or when there is reason to believe that the accused might attempt to evade justice. (b)Witnesses and other persons: When after twice being summoned to appear and give a statement, they fail to do so, and When the steps taken prove ineffective in obtaining the data for summoning them. 305.In no circumstances may the execution of the orders to locate and hand someone over involve acts of detention. 306.Moreover, the circular states that compliance with location and handover orders is to be enforced by the General Headquarters of the Judicial Police and officers of the various Judicial Police stations, who must do so with respect for the persons’ dignity and human rights, as per the Constitution of the United Mexican States, the Code of Criminal Procedure for the Federal District, the Act Governing the Use of the Armed Forces, the operating manual of the Judicial Police and other regulations governing their operations.Any act in contravention of the above will incur the appropriate administrative and criminal liabilities. 307.Consistent with this, Judicial Police officers are to comply with location and presentation orders, taking all appropriate action to that end, and once they locate the person, are to act as follows: Identify themselves to the person; Inform them of the reason for their presence, showing them the relevant order and explaining the reason for it; In the case of an accused person, inform them of their right to be assisted by a lawyer when appearing before the relevant official, and Hand them over to the public prosecutor issuing the order.
