Delaware police say they are keeping an eye on this Sunday’s AAA 400 in Dover following the arrests of three people suspected in a terror plot in Denver and New York City. The News Journal in Wilmington reports that state police met with NASCAR officials on Tuesday and had a conference call with the FBI. No specific threat has been identified.

Said state police spokesman Sgt. Walter Newton, "The Delaware Information Analysis Center is monitoring the situation in New York with the individuals arrested for alleged terrorism charges. Obviously, with the NASCAR event in Kent County, we will be monitoring the situation because, as you know, terrorists like to target large events, transportation systems and critical structures." Newton said there are "no viable threats" in the state. Racing events are scheduled Thursday through Sunday at Dover International Speedway, culminating with the AAA 400 on Sunday.
