TULSA, Okla. Students at a north Tulsa elementary school that was locked down for nearly two hours have been released to their parents.
Police say Celia Clinton Elementary was locked down with the children inside about 2 p.m. Tuesday when gunshots were reported near the school.
Earlier, authorities were responding to call of shots fired near the school, CBS affiliate KOTV Tulsa reported.
According to a spokesperson for the Tulsa Public Schools, the shots did not happen on the property of Celia Clinton Elementary School.
Tulsa Police Officer Leland Ashley says a group of parents were outside Celia Clinton Elementary about 2 p.m. Tuesday when they heard gunshots and saw a man in a yard just north of the school firing a weapon. The parents ran into the school and notified staff who called police.
Ashley says no students are injured and there is no indication the man was shooting at the school -- but that it wasn't clear what the man was firing at.
Ashley says officers are searching the area and nearby neighborhoods for the man who he said is about 5-feet-8- and wearing dark blue hooded sweatshirt and blue jeans.
Parents arrived at the school to pick up their children, said KOTV.
The man was still being sought late Tuesday afternoon.
The incident comes nearly one week after 26 people -- 20 of them children -- were killed in a mass shooting at Sandy Hook Elementary School in Newtown, Connecticut.
