On Tuesday, road blocks were set up to seal the area and police put up notices asking people who participated in the demonstration to turn themselves in, Zhang Zilin, a local human rights activist, told The Associated Press.
Other villagers said local officials were visiting homes and telling people to keep calm and stay off the streets.
"Things have calmed down today because they sent armed police forces with guns and metal rods last night," one resident told the AFP news agency.
She added that PAP officers were seen beating people in the streets on Monday night.Student 'severely beaten'
The Chinese overseas website Boxun.com, which frequently carries reports of unrest in China, said one middle-school student had been severely beaten and died in hospital.
Zhang said he did not have any details about the student who died, but Hong Kong's South China Morning Post
newspaper said the boy was hospitalised on Sunday and died on Monday.
Local police declined to comment officially on the situation but staff at the Public Security Bureau's Lingling District headquarters told AFP that all officers were out on the streets.
"It started from March 9 and is still going on. No one can comment on the event as almost all the policemen at our bureau are out there," said a staff member, who refused to provide her name, said.
The protests began after a bus station employee began beating a student after a dispute over a new five-yuan (63 US cent) baggage fee, the resident told AFP.Bus prices dispute
Another resident said people had been angered by bus fares being increased from six yuan to up to 15 yuan.
Government officials said on Tuesday it would be brought down to five yuan.
The incident is the latest outbreak of public unrest highlighting the problems in China's economic transition.
Anger over perceived corruption, land seizures and rising prices sparked tens of thousands of "mass incidents" last year, according to official figures, and the country's leaders have made a more "harmonious" society a top priority.
The ruling Communist party has in recent years focused its efforts to develop the poverty-stricken countryside and improve the lives of its 800 million rural residents.
