A child was “seriously injured” by a falling tree branch at Franklin Park Zoo on Tuesday, according to State Police.

Troopers responded to the Boston zoo at around 12:45 p.m., for a report of a falling tree branch that “struck and seriously injured a school-aged child,” police said.

Boston EMS transported the child to Boston Children’s Hospital.

An adult accompanying the child on their visit to the zoo was also injured, and was transported to a local hospital.

The incident remains under investigation by Mass State Police.
