Faculty and staff are on high alert at Specht Elementary School after an unidentified man walked onto campus with a sack filled with toys Friday morning.

The man approached students, who were on the playground, and started handing out the toys.

Teachers on duty immediately asked the man to leave and notified the front office.

The Bexar County Sheriff’s Office was also notified.

The district and the sheriff’s office are working together to properly respond to the incident, school officials said.

The district will also increase adult supervision on the playground at all times.
