criminals had the right to exchange letters and to meet members of their families. Under article 26, all detention establishments must have medical and pharmaceutical facilities. Sick prisoners had the right to treatment: if hospitalization was necessary, prisoners were treated in local hospitals; in cases of serious illness, prisoners might be released on bail. No cases existed of prisoners being held incommunicado, except where it was necessary to segregate male and female prisoners, adult and young prisoners, or certain categories of prisoner from other inmates. 16. Regarding paragraph 14 of the Chinese report, there had been cases - albeit very exceptional - where, in the interests of the investigation or to prevent the release of information or complicity, families were not notified of a person's arrest. In normal circumstances, the public security organs would inform the families. It was very rare for families not to be notified of an arrest on the grounds that such notification would hinder the investigation. 17. Regarding paragraph 46 of the report and the question of conclusive evidence, some members of the Committee had asked how, if no trial had yet taken place, conclusive evidence could be said to exist. The question was a good one: the matter had not been well expressed in the report. Article 41 of the Criminal Procedure Law provided that a public security organ might detain an active criminal or suspect (i) if he was preparing to commit, was committing or was discovered after having committed an offence; (ii) if he was identified by the victim or an eyewitness; (iii) if he had incriminating evidence about his person or in his residence; (iv) if he attempted to commit suicide or escape; (v) if he destroyed or falsified evidence, or colluded in CAT/C/SR.51 page 5 
**Analysis**
The text appears to be discussing the treatment and rights of prisoners, including their access to medical care, contact with family members, and notification of arrest. It also touches on the topic of evidence and the investigation process. These topics are related to the administration of justice and the protection of human rights, rather than economic or environmental issues.
