Christopher, the Montevideo police chief, said officers were called to the Rogers’ home about that flag.
‘‘Residents were very upset by that. They felt it was really a disrespectful thing to the flag, but it’s not illegal,’’ Christopher said. He said the family told him the upside-down flag was a ‘‘sign of distress because the country is in distress.’’
When asked if he believed a threat was imminent, Christopher said: ‘‘That’s always hard to say. My take on it is, when somebody has made explosive-type devices, the potential is there.’’
Christopher also declined to comment about the target of the alleged plot, but said the general public is not in danger.
