An off-duty officer working at Hirschi said he heard about a student possibly having a gun.
He detained 17-year-old Trashawn Dorsey and during a pat-down, the deputy said he felt a possible handgun.
The officer said Dorsey admitted to having a BB gun.
He says he was asked by another student to bring the gun to school for protection.
During the search, the officer said he also found .5 ounces of marijuana.
A 16-year-old Hispanic male is also behind bars for allegedly making threats to another student.
Two students have been charged following a lockdown at Hirschi HIgh School this morning.
Principal Doug Albus sent out an alert just before 10 a.m. saying that the school was placed on lockdown due to criminal activity near the campus.
Wichita Falls Police say the incident was the result of someone seeing a student with what appeared to be a gun.
Police responded and took two students into custody, one of which is a juvenile.
Authorities say the two will be charged with making terroristic threats.
The lockdown was lifted by 10:45 a.m.
