Tulsa police say a 25-year-old man died on Sunday night after a crash on Sheridan Road Near 27th Street.
According to investigators, the man left a nearby apartment complex after an argument with others and caused a collision.
They say he got out of his vehicle and began running around trying to start fights in the street so others restrained him.
It was then that he went into a seizure, police say, so the bystanders let him go.
As EMSA arrived, he was coming out of the seizure and was able to communicate with them before going into cardiac arrest, police say.
He was transported to a Tulsa hospital where he was pronounced dead.
At this time, police aren't sure if his cause of death had anything to do with the crash or if he was under the influence of something or it was a coincidental medical episode.
