Jeffrey Williams has been arrested in connection with the shooting of two police officers in Ferguson, Missouri.
Jeffrey Williams, a 20-year-old African-American, has been charged with two counts of assault and gun violations.
The police officers were wounded when shots were fired at them during a protest on March 12.
Ferguson has been a flashpoint for race relations following the shooting of black teenager Michael Brown by a white police officer in August 2014.
Giving details of the arrest, County Prosecutor Robert McCulloh said Jeffrey Williams had admitted to his “participation in firing the shots”, but added, “it was not certain if he had been targeting police”.
The prosecutor said that Jeffrey Williams claimed he fired the shots from a car in a dispute with other unidentified individuals.
Jeffrey Williams, an, had taken part in the peaceful demonstration earlier in the evening outside police headquarters.
The protest followed the resignation of Ferguson’s police chief after a Department of Justice report found racial bias in his department.
The police officers were wounded in the cheek and shoulder, and have since been released from hospital.
President Barack Obama and Attorney General Eric Holder condemned the attack.
Police chief Thomas Jackson was the sixth Ferguson official to be fired or step down. He had initially resisted calls from protesters and some state leaders to resign.
Thomas Jackson was widely criticized after the shooting of 18-year-old Michael Brown in August and the weeks of demonstrations that followed.
The DoJ report found substantial evidence of intentional discrimination in the police and justice system.
The report contended that African-Americans were at the receiving end of 90% of officers’ use of force.
In November, a St Louis County grand jury found that white police officer Darren Wilson did not break any laws when he shot Michael Brown.
Police across the country have faced criticism following the deaths of a series of black men in contentious circumstances.
