Police took 16 young people off the streets on the first night of a curfew crackdown in response to escalating violence, officials said.
The curfew in the Connecticut capital bans anyone under 18 from loitering on the streets after 9 p.m., unless they are with a parent or guardian.
Police Chief Daryl Roberts said curfew violators were taken to their homes and enforcement of the long-standing curfew went without incident Thursday night. He said there were no reported shootings in the city of 125,000 residents.
Police have said the curfew ordinance will be enforced for 30 days.
The announcement followed a violent weekend during which 11 people were shot. Seven of the victims were wounded in gunfire that erupted after Saturday's West Indian Day parade. A 21-year-old man was killed, and the wounded included a 7-year-old boy and 15-month-old girl.
City officials initially said that curfew violators would be detained at community centers, but backed off that plan after the American Civil Liberties Union of Connecticut said it would violate youths' rights. But officials said violators could be placed in state custody if they are picked up by police and there are no responsible adults at their homes.
An ACLU attorney, David McGuire, said the group opposes juvenile curfews because they violate the fundamental rights of innocent people. He said there were no immediate plans for legal action against the city.
