Police in Manor, Texas, which is 15 miles east of Austin, said the Manor Independent School District discovered video footage of the students at Lagos Elementary School playing near the bat on Monday.
The state Department of State Health Services tested the bat, which tested positive for rabies.
The families of the children were alerted and urged to see a doctor, KXAN-TV reported.
The school’s campus will be screened and inspected for more bats. It was shut down earlier this week after a staffer tested positive for the coronavirus.
Messages to the school district from Fox News were not returned.
