HOUSTON -- School officials say five students at a YES Prep school in southeast Houston were bit by a stray dog Tuesday.

It happened at the YES Prep on Crenshaw Road east of Galveston Road.

Serious injuries were not reported. The students, who are in the 7th grade, were treated by EMS and then released to their parents. None were taken to the hospital.

Teachers and staff managed to round up the dog and contain it in a car in the parking lot until HPD arrived. Animal control was then called in to pick up the dog.

School officials are trying to figure out how the dog got onto school property in the fenced in area.

YES Prep Public Schools issued the following statement Tuesday afternoon:

Maintaining a safe and welcoming learning environment is a top priority of YES Prep. Today, unfortunately, some of our middle school students were bitten by a stray dog during their outdoor recess at approximately 12:20 pm at our Southeast campus. Thankfully, our staff acted swiftly to contain the dog and take students to safety. Emergency personnel were immediately contacted and reported to the campus to treat injured students awaiting the arrival of their parents. No students have been transported to the hospital and all have gone home with their parents. Control has removed the dog from the premises and the Houston Police Department is investigating the matter. We will work with all authorities to prevent a similar incident from occurring in the future and wish our students a speedy recovery.
