A 14-year-old Boston Latin School student was seriously injured Wednesday afternoon when he jumped into the path of an oncoming Red Line train at Shawmut Station in Dorchester, Transit Police said.

MBTA Transit Police Superintendent Richard Sullivan said the teenager was injured on the southbound side of the subway station at about 1:50 p.m.

“It looked gruesome, very gruesome to watch,” said Marlena Rivera, 30, of Roxbury, a witness.

The boy “intentionally entered into the right of way as a Red Line train was approaching” and came into contact with the train, Sullivan said.

“He sustained serious injuries, ” Sullivan said.

The teenager was taken to Boston Children’s Hospital, according to Boston Emergency Medical Services.

Sullivan didn’t identify the student, nor did the head of the Boston Latin School in a statement issued Wednesday evening.

“Due to student and family privacy we are not able to provide any further information,” Jason P. Gallagher, head of school, said in an e-mailed statement. “We will continue to keep the student and their family in our thoughts and offer whatever support and assistance is needed.”

Counselors will be available to speak with students and staff “who need support and would like to talk to a trusted adult,” the statement said.

“Please know that our school is here to support our students and staff,” Gallagher wrote.

Shuttle buses were put into use between Ashmont and the JFK/UMass stations in Dorchester while police processed the scene. At 4:26 p.m., the MBTA announced regular Red Line service had resumed.

Rivera said she observed the boy being carried from the station on a stretcher. Hisface was badly swollen, he wasn’t moving “at all whatsoever,” and rescuers were treating him with an IV, she said.

The station was evacuated, according to Rivera.

“It was a bit scary, scary to see the person’s face look very swollen” on the stretcher, Rivera said. “I’ve been here my whole life and riding these trains since I was 10 years old. I never in my life saw anything like this happen, ever.”
