Several Team GB officials have praised the security protocols in place at this year's Winter Olympics in Sochi.
Speaking at a press conference in the Russian resort, Lord Coe told reporters: "We haven't been appraised of any particular situation. We are in permanent contact with all the agencies you would expect us to be in contact with. I'm unaware of any overtures that have been made to us.
"The balance of security on the torch relay I witnessed today was absolutely pitch perfect. I think that is a good omen for the rest of the Games."
Meanwhile, Sweeney said: "Our threat level has not changed since we came out, we are not aware of any specific threats but we are monitoring the situation."
Earlier today, the United States government warned airlines flying into Russia that explosives could be hidden in toothpaste tubes and smuggled on their aircraft.
