Beijing police have paid out more than 2 million yuan (about 317,000 U.S. dollars) in rewards to informants this year, the force revealed on Saturday.
A spokesperson said more than 1,700 citizens have received cash rewards.
In Beijing's Xicheng District, members of the public have provided more than 720 tips, which helped police to uncover about 270 criminal acts and detain 340 people. In Dongcheng District, 1,000 people were questioned or detained by police acting on public tips-offs.
"Many members of the public are active in ensuring security in their communities. It is customary for the police to reward those who help officers to maintain security and stability," the spokesperson said.
Beijing has mobilized 850,000 residents to patrol the city to ensure security ahead of a military parade commemorating the end of World War II on Sept. 03.
