OSHKOSH - One person was injured after police responded to a report Friday afternoon of a man with a gun near Oshkosh North High School.

While responding to the call in the 2100 block of Wisconsin Street, officers heard a single gunshot about 1:30 p.m., according to Oshkosh police. They found the man in a backyard with what appeared to be a self-inflicted gunshot wound, Capt. Kelly Kent said.

Authorities were preparing to lock down the school, but since the situation was quickly resolved, a lockdown was not necessary, Kent said. He declined to release more information about the severity of the man's injuries, citing the nature of the incident and pending notification of the man's family.
