A 13-year-old Ypsilanti Lincoln student remains in critical condition after being shocked at an eighth grade football game held at Lincoln High School Tuesday night, officials said.

The boy was at his brother's football game and playing catch with someone on the sidelines near the bleachers when the incident occurred around 8:30 p.m., said Augusta Township Fire Chief Vic Chevrette.

"There were several juveniles, not associated with the football game, playing catch with a football near the stadium's handicap access ramp," Michigan State Police said in a release. "While playing catch, the football was thrown over a nearby fence. The juvenile victim went to retrieve the football. One of the other juveniles noticed the juvenile victim lying against the fence and went to check on him. The juvenile observed the victim in distress and called for help."

Chevrette said the boy received the shock when he leaned against the fencing of a metal bleacher ramp.

“We don’t know how it was energized," Chevrette said.

A 40-year-old woman was also shocked when she reached down through the railing to help the boy, officials said. She was treated at the scene.

It was the same ramp a few hundred people walked up to get into the bleachers to watch the game, according to Chevrette.

An off-duty Augusta Township firefighter and nurse who were in the crowd immediately administered CPR.

The boy was then taken to C.S. Mott Children's Hospital in critical condition, according to Joyce Williams of Huron Valley Ambulance.

Power was immediately turned off at the stadium. DTE Energy officials were called to the scene, as well as the Michigan State Police.

State fire officials were at the scene Wednesday morning trying to determine how the metal bleacher ramp shocked the boy, Chevrette said.

State police said they were going to issue a press release Wednesday morning. This story will be updated when that occurs.
