Everards managing director, Stephen Gould, said: "We were placed in a position that throughout the day our staff had to respond to very aggressive people obviously believing that the policy was true.

"Ourselves and the manager will have to monitor that very, very carefully over the coming days."

He added: "We have no idea why The Globe was targeted but we will be working with police to find out why this happened."

Police confirmed the matter was under investigation and urged anyone with information about the posts to contact them.
