BEIJING - The number of criminal offences by seniors jumped more than 38 percent in one Beijing district from 2008 to 2010, a reflection of the country's fast-growing gray population.

The Beijing Haidian District People's Court settled 18 criminal cases involving suspects aged 60 and above in 2008.

But so far this year the court has handled 25 such cases, said Chen Ming, a judge who compiled the report.
