Worcester police responded to a chaotic scene Sunday as gunfire rang out during the city’s Caribbean Festival, sending two victims, 15 and 23, to the hospital.

Police said the gunfire erupted at about 6 p.m.  Officers assigned to the festival at Institute Park responded to the shooting at the area of Salisbury and Boynton Streets.

“This caused a chaotic scene in which the large crowd was attempting to run to safety,” Worcester police said.

Responding officers were able to identify the victims and provide first aid until they were transported to the hospital. Police said the injuries appear to be non-life threatening.

According to the initial investigation, police said the victims appear to be innocent bystanders otherwise unrelated to the shooting.

Police described the shooting as an “exchange” of gunfire that arose from a  dispute on Boynton Street near the intersection with Salisbury Street, according to investigators. The shooting remains under investigation.

The shooting at Worcester’s Caribbean festival comes a day after gunfire erupted on a Talbot Street lot adjacent to Boston’s Caribbean Carnival celebration Saturday, injuring 8.

Police in Boston have arrested 4 in connection with the investigation of that shooting and the incident remains under investigation.
