A number of Connecticut museums closed their doors Saturday after the Mystic Seaport Museum and Florence Griswold Museum received separate bomb threats.

Whether the threats were connected remained unknown Sunday as the museums reopened to the public.

Joshua Campbell Torrance, the director of the Florence Griswold Museum in Old Lyme, said a bomb threat was emailed Saturday to a staff member and public-facing account for general museum inquiries.

“Once we got that threat, we closed the museum, evacuated the museum, and took our lead from local and state police,” Torrance said.

A representative of the Connecticut State Police Media Relations Unit said local patrol officers deemed the threat non-credible after observing “nothing suspicious” during a “thorough check of the building” that was assisted by museum employees.

As a result, the state police bomb squad did not respond to the scene, the representative said.

Torrance said that after receiving the all-clear from police Saturday, the museum “elected to stay closed and let everyone catch their breath.”

“We’re super appreciative of the help of our state and local officials who helped us navigate the situation,” Torrance said. “Our paramount concern is the health and safety of our visitors and guests, and our state and local officials helped us ensure that process.”

State police said the FBI would conduct a follow-up investigation.

Stonington police said officers evacuated a “very small number” of Mystic Seaport visitors and staff after the museum received a bomb threat Saturday morning.

Canine units from Westerly and Mashantucket police departments assisted in the search, Stonington Deputy Chief Todd Olson said.

Olson said the Mystic Seaport property was cleared, and the museum was closed for the day. The case is under investigation.

On Sunday Olsen said he “was not sure of any connection” to the bomb threat made to the Florence Griswold Museum.

Sophia Matsas, Seaport vice president of marketing and communications, confirmed that the threat was communicated through an email.

“We quickly implemented our emergency protocol and engaged local law enforcement to ensure the safety and well-being of our staff, visitors and community, which is our top priority,” Matsas said. “Stonington Police determined the threat was not credible, but the Museum was closed for the remainder of day out of an abundance of caution. We have since reopened.”

Other museums closed Saturday after hearing reports of threats to institutions along the shoreline.

The New Britain Museum of American Art canceled its annual gala Saturday night although it did not specifically receive a threat.

“Our board deliberated for about an hour yesterday and decided we just couldn’t, in good conscience, have several hundred people gathering for a joyous occasion with other institutions, so close by, receiving security threats like that,” Lisa Lappe, the director of Communication and Visitor Experience for NBMAA, said. “We were just being overly cautious.”

Lappe said after a check of all security cameras and a property sweep by local authorities, the museum opened Sunday with hourly entrance and ground checks.
