A West Texas school district has beefed up security after last week's pot find on a Van Horn school bus.
The Superintendent of the Culberson County-Allamoore School District says a letter will be mailed to parents on Tuesday.
It will detail a plan which includes a checklist for busses, tightened security at the bus barn and coordinating safety with neighboring school districts.
Nearly 500 pounds of pot was found in duffel bags in the cargo area of the bus, which was hauling Van Horn basketball players heading home from a game in Presidio.
The driver found the bags during a stop at a convenience store while refueling in Marfa.
No arrests have been made.
