GREEN BAY (WFRV) - Police say an intoxicated driver struck a gas pump at a Speedway on the city's East Side Sunday morning, then took off on foot. The crash happened on the corner of Victoria Street and East Mason Street. The driver, a 43-year-old man, is behind bars. Police later found the man with the help of a good Samaritan who flagged them down. "I heard a screech and a crash," Joshua Nelson tells Channel 5's Hilary Golston. Nelson says he ran toward the car and helped the man get out. He even hurt his hand trying to break the glass. Nelson says he could see the man was under the influence. "He was definitely intoxicated. It was pretty bad," Nelson said. "He was kind a tipsy. He was incoherent." Later, Nelson took his car and went looking for the suspect. He helped flag police down. "I was walking and I was trying to find him," Nelson said. "I found him." Onlooker Nathaniel Slack tells Golston he took a fire extinguisher to help get the man out and tried to put out the flames, despite concerns of a gas explosion. "My fiancé was on the side walk telling me to come back," Slack said. "She didn't want me getting hurt." Police are holding the driver on obstructing an officer, operating under the influence, hit and run and operating without a license. Channel 5's HIlary Golston reports.
