FRISCO, Texas (CBSDFW.COM) – School administrators in Frisco decided they will reopen Lone Star High School on Wednesday after a social media threat kept the campus closed this week.

“We appreciate your patience and understanding during the closure,” the district said in a letter to parents.   “Over the last two days, the Frisco Police Department completed an extensive K-9 and officer sweep of the Lone Star campus and did not find anything that posed a threat or was suspicious.”
