Chinese police in 2016 arrested 4,261 suspects in 1,886 cases related to infringement of citizen's personal information, the Ministry of Public Security said Friday.
Among the suspects, 391 were insiders in industries including banking, education, telecommunications, delivery services, the stock market and e-commerce, said the ministry.
The ministry also said police seized 1,747 suspects involved in 828 cases related to hacking.
Personal information infringements have increased in recent years, leading to a rise in fraud and racketeering, according to the ministry.
