Bloomberg was already scheduled to travel to Berlin Tuesday to accept the 2010 Henry A. Kissinger Prize. The city said Friday the mayor added a stop in London that morning.
Bloomberg plans to tour a closed-circuit television facility in London to examine its "ring of steel" surveillance program. The network of cameras was the inspiration for a 3,000-camera system being installed in lower Manhattan. A similar system is being planned for midtown.
Some have pointed to the Times Square bomb plot last week as another example of why the city needs such surveillance systems.
