Juveniles, aged between 14 and 25 years, accounted for 44 percent of the total number of people who committed crimes in the first half of this year, an increase of 1.6% over the same period last year, reported Beijing-based Economic Daily.
Juveniles involved in violent crimes accounted for 70 percent or more of the total, the paper said.
"The rate of juvenile delinquency has kept increasing. Parents have to take it seriously," Wu Heping, spokesman for the Ministry of Public Security, was quoted as saying.
Some teenagers have used the Internet to commit crimes, Wu said.
"How to prevent juvenile delinquency? Family education is most important," he said. "We found that parents who divorce and domestic violence tend to produce children with a higher likelihood of committing crimes."
The prevention of juvenile crime requires coordination by families, schools and the public, Wu said, adding that the ministry has launched a special campaign to clean up the surroundings of schools and has sent high-quality police officers to work as assistants in schools."
