When they tried to pull over the driver over, they say he took off.
Another cruiser joined in the chase eastbound on Route 46.
Within minutes, the driver, who police identify as Israel Curbelo, approached the GWB.
He hit a car, was thrown from the bike and died there in front of the bridge.
One man told me his brother was one of the bikers.
He said he was with him until 1:00 Friday morning in New York City, so he had no idea what happened between then and the time of the chase.
Traffic was immediately backed up, and remained that way through the morning rush.
The Bergen County Prosecutor is leading the investigation. According to the prosecutor's office, police detected alcohol on Curbelo when they were trying to revive him. They say they also found marijuana on him.
The big question now is did police follow the proper guidelines for a police chase?
The prosecutor's office will now have to figure that out.
