After being shot in the face with a homemade gun, a man repeatedly hit the shooter with a brick during a wild confrontation between known foes at a busy intersection in Changsha, Hunan Province, on Thursday morning.

Both men survived the fight and have been detained by police.

A witness said the gunman and several other men who carried metal chains used their Mitsubishi SUV to block another car at an intersection on Wanbao Avenue in Furong district at around 11 am, reported peoples.com.cn, the website of the People's Daily

Police say the gunman surnamed Peng, 36, fired two shots, one of which hit Li, 42, in the face.

According to the report, Li was not seriously wounded and attacked Peng with a brick as several other of his cohorts arrived to join the melee.

Li knocked Peng unconscious with the brick and continued to pummel the bloodied man until police arrived.

The other men involved in the fight fled the scene in their vehicles and on foot before local police arrived on the scene.

Local police said on their official microblog that Peng and Li fought over a debt and had attended a court mediation session earlier in the day, where they obviously failed to reach a settlement.

A police press officer surnamed Jiang from Furong district told the Global Times that the two men miraculously suffered only minor injuries.

He said police are still looking for the men who fought with both Li and Peng.

Jiang said he could not provide additional details as the investigation is ongoing.
