CHENGDU: Peace has returned to a high school in Gulin county, Sichuan province, in the wake of a student uproar that led to the removal of its headmaster and an investigation into possible corruption on campus.

During a heat wave lasting several days, power was cut off several times at the State-owned Linyang High School, built in 1972.

Around 11 pm on Sept 10, the dormitory administrator first cut off electricity for girl students.
