A man accused of going on a rampage in his car and ramming other cars at Lambeau Field Friday had been involved in a physical fight with one of his intended victims a few weeks ago, a criminal complaint says. Chay Vang, 40, was charged in Brown County Circuit Court Tuesday with two felony counts of first-degree recklessly endangering safety and five misdemeanor counts of damage to property. Court Commissioner Jane Sequin set a $10,000 cash bond and scheduled his next court appearance for Jan. 9. Vang was working for Delaware North at Lambeau Field several weeks ago when he got into a physical altercation with 25-year-old co-worker, the complaint says. The man told police they got into an argument in a freezer during the Green Bay Packers' Dec. 3 home game, and it escalated into pushing. "Chay then punched me in the face and I defended myself," the man told police, according to the complaint. Delaware North investigated the incident and fired Vang, the complaint says. About 1 p.m. Friday, the man and another co-worker had finished eating lunch in a car in the employee parking lot at Lambeau Field and were just getting out of the car when Vang confronted them, the complaint says.
