A 16-year-old boy died after getting shot twice in the chest in a drive-by shooting on the street on the side of his high school Tuesday morning, police said.

He died on arrival at Ben Taub General Hospital, said Evelyn Flouri, an officer with the Houston Police Department. Police were not releasing the victim's name.

Westbury High School was in session at the time of the shooting, said Houston Independent School District spokesman Terry Abbott. No one else was injured.

Police have not identified suspects or determined if the incident was gang-related.

The school district is planning to beef up security at the campus, which has three full-time officers based at the school and others patrolling around the campus every day, Abbott said.

"This is one of the best guarded schools," he said. "We are going to increase the patrol for the foreseeable future."

Westbury has been involved in a handful of violent incidents in the past year. In April, a school bus taking students home from the high school and a middle school was shot at and two students suffered minor cuts from glass fragments.

In December, 15 Hurricane Katrina evacuees who were attending the school and 12 local students were arrested during a near-riot in the lunchroom.

Almost seven in 10 students who attend the school qualify for free or reduced lunch, a marker of poverty.
