HONG KONG (REUTERS) - Chinese security forces fired tear gas and beat protesters in a village in southern China on Sunday to quell a grassroots protest movement over a land dispute, residents said.

Dozens of villagers were taken to hospitals in Mianhu town and Jieyang city and five people were arrested, witnesses said.

A large contingent of riot police and other security personnel moved into Shangpu village in southern Guangdong province early on Sunday morning, said several residents contacted by Reuters by telephone and on microblogging sites.

"They didn't say a thing and started firing teargas and beating villagers with truncheons," said a young villager who witnessed the incident.

"They had torches on their helmets, like miners, and were hitting some old people with truncheons who were sleeping in tents. They gave no warning."

Gongs were sounded and hundreds of villagers charged out to help those being beaten but were forced back by some 3,000 security personnel and volleys of teargas, villagers said. The unrest in Shangpu was triggered over a land deal involving some 33 hectares of rice paddies on the outskirts of the village that were leased cheaply to a firm called Wan Feng for 50 years to build an electric cable factory.

The deal, made without majority village consent, was brokered by Shangpu's village committee chief Li Baoyu, according to a signed contract seen by Reuters.

The villagers want the contract scrapped, their land returned and Mr Li fired.

In late February several hundred men, armed with steel pipes and spades, threatened the 3000-strong village to accept the land deal. Villagers, however, retaliated, chasing the men away and destroyed over 20 of their jeeps and cars.

The villagers refused to allow authorities to clear away the gutted vehicles, demanding the land deal be scrapped first.

But early on Sunday, however, tow trucks cleared away most of the vehicles from a highway outside the village. A small number remained on the main street.

"We tried to stop them from doing this...If they tow away the cars, they won't do anything anymore," said a villager.

A senior villager, who delivered a written indictment against the land sale to provincial leaders including Guangdong governer Zhu Xiaodan, said he was shocked and disappointed with Communist Party authorities for cracking down in this manner.

Authorities in nearby Jieyang city have verbally agreed to scrap the land deal, senior villagers say, but they have not yet been offered written proof of this.

The situation in Shangpu is similar to that of another high-profile standoff over land seizures in Wukan village, about an hour's drive away - that openly revolted for several months over murky land sales in 2011. Like Wukan, Shangpu villagers are also calling for elections to vote in a new village leader.
