Oakville residents near the Black Forest subdivision and apartments took to social media around midnight Friday morning to ask: Why is there a police helicopter searching for someone?

An initial post estimated there were 30-plus police cars in the area. Other residents said entire streets were blocked by police cars.

“I’ve lived in Oakville all my life, very upsetting to see all this crime here lately,” one resident said.

Residents reported that police knocked on their doors and told them to stay in the house, leading to the impression that the suspect police were searching for was either a violent criminal or wanted for a major crime.

We asked the St. Louis County Police Department’s spokesman Sgt. Shawn McGuire for an answer.

“Last night was a pedestrian check, that turned into a foot pursuit, which led to a warrant arrest,” McGuire said Friday.

And it does not appear that the person was wanted for a major crime, he added.

It was an eventful week for crime in south county.

The county police also took out their police helicopter in south county Thursday for another foot chase of a man wanted for stealing an SUV in Jefferson County who crashed the stolen SUV and took off when the Sunset Hills Police Department tried to pull him over.

The Oakville incident also happened just days after an armed robbery while a woman was in her house on Milburn Road in Oakville and an armed carjacking of a couple at the Butler Hill Schnucks.
