Broken Arrow High School was on a brief lockdown Wednesday after a possible gun was reported on campus.
Broken Arrow Police Officer Chris Walker said the precautionary lockdown went into effect about 1:30 p.m. and was lifted at 2 p.m.
Police in a news release said one student reported another student was in possession of a firearm on campus.
"Broken Arrow Police are currently interviewing all involved parties to determine if there is any credibility to the allegations," the release said.
"Out of an abundance of caution, district security personnel placed Broken Arrow High School under a brief lockdown this afternoon while administrators worked with the Broken Arrow Police Department to investigate an alleged threat involving a gun," BA Public Schools spokesman Charlie Hannema said in a statement.
"The lockdown lasted approximately 30 minutes and was lifted after it was determined a credible threat did not exist to Broken Arrow High School.
"As always, the safety and security of our students is our highest priority. We take any possible threat seriously and thank the Broken Arrow Police Department for their quick response and guidance."
