国际英语新闻:Violence erupts after police-involved shooting in U.S. state

CHICAGO, Aug. 14 (Xinhua) -- A confrontation between police and protestors turned violent Saturday night in Milwaukee in the north-central U.S. state of Wisconsin, after a police officer shot and killed an armed 23-year-old man.

A gas station and a vehicle were set on fire after some 100 protestors gathered near the scene of the shooting, a predominately African-American part of the city, and confronted with the police for about an hour earlier in the evening.

A police officer was hit in the head by a brick thrown through the car's windows.

Witnesses say gun fires were heard as police officers wearing riot gear tried to disperse the protesters. At least three people have been detained.

The shooting happened Saturday afternoon when two police officers pulled over a car with two suspects inside. The suspects then began to run. In a foot chase, a police officer shot and killed the 23-year-old, Milwaukee Journal Sentinel reported. The race and the name of the suspect or the officer remain unknown.

The police officer, who was not hurt, was placed on administrative leave while an investigation into his conduct has been launched.

The second suspect, also a 23-year-old man, has been in custody.

In a news briefing at the scene shortly after the shooting, Milwaukee Police Assistant Chief Bill Jessup said the man who was killed carried a stolen handgun and has "a lengthy arrest record," which he failed to specify.

Mayor Tom Barrett, appealing for restraint and calm, acknowledged that the neighborhood, where the shooting took place, has been affected by violence in the recent past.

"There are a lot of really, really good people who live in this area ... and can't stand this violence," Barrett said.

The incident was preceded by several police-involved shootings across the United States, in which the use of force by police is questioned.

In July, two black men were shot dead by police in Louisiana and Minnesota, which sparked angry protests by African Americans across the nation against police brutality and racial discrimination.

Earlier this year, a native American woman was killed by an Arizona police officer. The shooting has prompted protests in recent months by Native American activists.
