CAT/OP/MEX/1/Add.2 205. This mechanism is a tool for overseeing the conduct of the prosecution service to ensure that persons handed over to the Attorney-General’s Office are not held in custody beyond the statutorily permitted period. 206. The screens display the following information: • Preliminary investigation number; • Date and time of commencement of the preliminary investigation; • Name and age of the accused; • Prosecution unit conducting the preliminary investigation following arrest; • Offence with which the detainee is charged; • Countdown clock showing the time remaining for determination of the legal status of the accused; and • Legal status of the accused. 207.

Thus, all premises of the public prosecution service in the Federal District now have this equipment. 208. The transparent prosecution service web programme was implemented in September 2010 as the second stage of the above programme. The web programme, which allows Internet searches to be made on persons handed over to the prosecuting authorities, provides the public with details of the prosecution division at which a relative or acquaintance is being held, the name of the head or person in charge of the division, a georeferenced map of its location and the charges against the detainee. 209. The Assistant Attorney-General’s Office, in collaboration with the company BlackBerry Latinoamérica, has developed an application for mobile devices which includes the prosecution service web programme and a directory of public officials of the AttorneyGeneral’s Office. 210. Through these programmes the public can acquire sufficient data to access the prosecution division in order to obtain further information, either via the web programme screen display or directly from prosecution personnel, thereby contributing to increased monitoring of arrests and the prevention of incommunicado detention. 211.
