A Chicago man was charged Wednesday in connection with a post-fireworks fracas that sent one man to the hospital, police said.

Ramen Griffin, 24, of the 5800 block of West Huron, was charged with battery after he was identified as an aggressor in a fight that broke out around 10 p.m. Monday, shortly after the fireworks display at Oak Park-River Forest High School.

According to Oak Park Police Cmdr. LaDon Reynolds, here's how it happened:

Griffin and the victim, an unidentified 31-year-old man from Chicago, were engaged in some sort of altercation when the victim started running across Lake Street.

Chased by Griffin, the victim fell face-first onto the pavement near Ridgeland Avenue. That's when Griffin "caught up to him and stomped him on the head then walked away," Reynolds said.

An Oak Park Police Sergeant who watched the scene "evolve" took Griffin into custody, police said.

Reynolds shot down speculation from witnesses who reported that the incident was a group beating.

"There was a substantial group in the area, but that group was a result of the egress from the fireworks show," he said. "This was between two individuals from Chicago. There were no other subjects involved."

The victim, who was unconcsious and bleeding when paramedics arrived to the scene late Monday, was treated at Loyola Medical Center in Maywood. According to TribLocal, he was released from the hospital Wednesday.
