The University of Oklahoma in US' Norman said that its campus is secure hours after the school had warned that there was an active shooter present. The University has lifted the emergency after authorities conducted a sweep of the campus and declared that no threat was found.
"OUPD has issued an ALL CLEAR. After a thorough search, no threat was found. There is no threat to campus. Alert has been canceled," the University of Oklahoma said in a tweet.
Earlier on Saturday, students were advised to avoid the South Oval area and to shelter at place as authorities searched the college campus for a shooter.
“There is an active shooter at the Van Vleet Oval. Take immediate action now. Run. Hide. Fight!” the college had tweeted earlier today.
Visuals on local media showed multiple police and SWAT tactical vehicles outside the University of Oklahoma.
The university president Joseph Harroz lauded the swift response by the law enforcement agencies.
"Our officers took immediate action, our emergency protocols worked, and our community was kept informed. Campus is safe," Harroz said.
The incident comes just days after two nine-year-old girls, a nine-year-old boy, two teachers and a school custodian died during a school shooting in Nashville.
School and college shootings are alarmingly common in the United States, where the proliferation of firearms has soared in recent years. There have been 129 mass shootings -- defined as incidents in which four or more people were shot or killed -- so far this year, according to data from the Gun Violence Archive.
Efforts to ban the powerful weapons have run up against opposition from Republicans, staunch defenders of the constitutional right to bear arms.
