Bomb Threat Closes Martha's Vineyard Airport

Martha's Vineyard Airport was shut down Tuesday morning due to a bomb threat, police say.

The Martha's Vineyard Times reports that the threat caused the airport to close at about 6 a.m.

It was secured and closed to both air and ground traffic. A dog trained to detect explosives was  brought in to sweep the area, Massachusetts State Police spokesman David Procopio said in an email.

Assistant Airport Manager Geoff Freeman said the airport was cleared by police and reopened at about 9:40 a.m., but travelers should expect residual delays.
