One person was killed and six other people, including a child, were injured in shootings on Saturday evening towards the end of the yearly West Indian parade and festival in Hartford, authorities said, as reported by the New York Times.

Three people allegedly connected to the incidents which took place at approximately 6.30 p.m. have been arrested, according to police officials.

However, the motive of the shootings remained uncertain. Furthermore, no information about the victims or the suspects was revealed, except the fact that a child had been among the injured people. The child’s gender was not specified, nor was his age.

The incident occurred at the end of the parade, an event which is held in the North End, an area where the majority of Hartford’s West Indian population lives.

According to the New York Times, a woman who attended the parade, Michele Redding, informed The Associated Press that she heard about ten shots, which sounded like fireworks. Furthermore, as reported by the same source, the woman said she saw a man fall and rushed to him in order to give him first aid. She told The Associated Press that he seemed to be in his early 20s and his breathing was labored while “the blood was gushing from under his arm.”

The event is attended annually by thousands of people from around the region and has been celebrated for more than 45 years.
