ONGOING PROTESTS

Throughout the day and into Sunday evening, protesters gathered on Florissant Street, knots of people on foot replacing those who had cruised slowly by in cars on previous nights.

It was not immediately clear whether the growing crowd would respect the Sunday night curfew. The prior evening, protesters were dispersed by police using canisters of smoke and later teargas after refusing to leave the area when the curfew began.

Seven protesters were arrested early on Sunday after failing to disperse as the midnight-to-5 a.m. curfew went into effect.

During the night, one person was shot and critically wounded. The circumstances were not clear, and the shooter was still at large, police said. Johnson said police were unable to identify the victim, who he said was not shot by police.

Johnson also said someone had shot at a passing police car and was not apprehended.

The smoke and teargas were "the minimum amount of force that we could have used to get them moving," said Missouri State Highway Patrol spokesman Al Nothum.
