SOUTH SIOUX CITY, Neb. -- Authorities are investigating an officer-involved shooting in northeast Nebraska Thursday. 

The Nebraska State Patrol said it is investigating the shooting, which occurred in South Sioux City.

According to the South Sioux City Police Department, the incident happened around 7:50 p.m., when officers were reportedly responding to a possible overdose at an apartment complex in the 300 block of E 12th Street.

NSP officials said paramedics had already responded but were forced to evacuate the location after a subject, 61-year-old Richard Germek, displayed a firearm.

An initial investigation indicated that officers arrived to the scene and tried to speak to Germek, but he fired the weapon at officers in the hallway of the apartment building. It was reported that an officer returned fire and struck the subject.

Authorities said that Germek was transported to a hospital in Sioux City with non-life-threatening injuries.

Germek was then lodged in Dakota County Jail after getting treatment.

Germek's charges are pending, and he has since been returned to the hospital for a medical condition unrelated to the incident.

It was reported that no officers were injured during the incident. 

The South Sioux City Police Department has requested that the Nebraska State Patrol investigate the incident.

This is an ongoing investigation.
