BERRIOZABAL, Mexico -- Scores of young prisoners threw stones and set
                 off homemade bombs in two days of rioting at a youth detention center in
                 southern Mexico. At least 20 people were injured.

                 About 400 police were brought in to control the rioting Monday and Tuesday at the
                 Villas Crisol center in Berriozabal, 11 miles east of the Chiapas state capital, Tuxtla
                 Gutierrez.

                 The youths, many of them high on paint thinner and liquid glue, said they were
                 protesting poor living conditions that include bad food, dirty water and a lack of
                 necessary medication.

                 Authorities said they had located at least four alleged leaders in charge of instigating
                 the disturbances.

                 Civil protection officials confiscated 50 bags of glue and at least 20 bottles of paint
                 thinner and alcohol, and were keeping the center under a 24-hour watch, said
                 agency deputy secretary Horacio Schoeder.
