Doctor Who and the Terror of the Thames

Today's papers report that there was an "event" during the new series production today... as the Daily Star put it, "A Doctor Who film crew had more than the Daleks to worry about when it was surrounded by antiterrorist cops on the River Thames." Apparently, the actors and production staff were filming on a boat in front of the House of Parliament, but the boat strayed to close to teh building, and police in high-speed patrol craft moved in and surrounded them! Our correspondent Mark Coupe writes, "[The Mail] is saying that apparantly there was some kind of flap over the last couple of days, where the crew on Doctor Who had been filming some scenes with River Police on the Thames and had somehow drifted into the area around the MI5 building (although surely its the MI6 one which is next to the river?) and caused anti-terrorist police to be rather concerned! Apparently, the crew from Wales werent au fait with all the river regulations." (Thanks to Paul Engelberg, Mark Coupe... and sorry for the news item title, but I couldn't pass it up!)
