SPRING -

Authorities said a Spring High School student was walking to school when he was hit by a Harris County sheriff’s deputy.

It happened around 6:30 a.m. Wednesday in the 2300 block of Spring Creek near Winship Elementary School in Spring.

Authorities said the deputy was off duty, but driving a patrol car when a 15-year-old boy, who was walking with two other students, was hit.

The deputy did not see the teens walking in the middle of the street.

The sheriff's office said it was dark outside, there were no street lights or sidewalks and the students were wearing dark clothing.

Officials said the boy was airlifted by Life Flight to Memorial Hermann Hospital with non-life threatening injuries. Police at the scene said the boy is expected to survive.

Police said the two other teens the victim was walking with did not stop and continued on to their bus stop. Deputies are at the school trying to track them down.

The deputy was not hurt, but he was shaken up. The sheriff's office said he has been with the department since 2004 and is assigned District 2 Patrol.

The Harris County Sheriff’s Office Traffic Enforcement Division is investigating this accident.
