State Police bomb squad personnel closed off an area around a Logan International Airport terminal for about an hour Sunday night as they investigated a suspicious package, authorities said.
Terminal C, which serves JetBlue, United, and Cape Air, was shut to vehicular traffic for about one hour before the package was cleared; normal operations resumed at about 9:40 p.m., State Police Lieutenant Dan Richard said.
Massport spokesman Richard Walsh said the terminal was not closed or evacuated while the package was investigated.
Authorities did not provide further details.
Lynne Godfrey of Medford said people were ordered to stay in a baggage claim area inside the terminal for about 30 to 40 minutes, but officials did not explain why.
One passenger said that shortly after his flight landed at Logan Sunday night, he found himself walking a short distance from a robot approaching the package and snapped a quick photo, which he then tweeted.
The man, Dave, who asked to have only his first name published, said he was walking along an outdoor airport pedestrian ramp heading toward a rental car pickup area when he glanced down and saw the robot, surrounded by several orange cones, moving toward the package, which was on a cement wall.
“I didn’t look too hard — I got nervous. So I just took a picture quickly and left,” he said.
He said that State Police troopers ordered him and others to clear the area.
“They were saying, ‘You have to move, move, evacuate the area,’ ” he said.Matt Rocheleau can be reached at matthew.rocheleau@
