Crime is falling on London buses and Tube, but muggings up
Latest figures show an overall drop in crime on London buses and the Tube - but a slight rise in robberies on the bus.
Crime on both the Tube and bus fell by about 10%, a drop Mayor of London Boris Johnson attributed to more officers on the network.
But bus muggings were up by 4.5%, from 2,665 in 2010-2011 to 2,783 in 2011-2012.
Labour called the rise "deeply concerning".
Labour's crime spokeswoman Joanne McCartney said: "The dramatic rise of muggings on London's buses is deeply concerning.
"While it is good news that other types of crime are falling it is very worrying that this type of often violent crime is rising."
Labour pointed to bigger rises in bus mugging in some London boroughs as evidence of a growing problem.
Haringey saw a rise of 86%, Sutton 61% and Hounslow 52%.
Hailing the overall fall in crime, Conservative Boris Johnson said: "With more officers on the network, my teams have worked tirelessly to crack down on crime on our transport system, and to keep it down while passenger numbers soar.
"Nevertheless, we are not complacent and while these figures are encouraging, more can be done and we will not relent from our focus on making stations safer, ensuring uniformed officers are highly visible on public transport and curbing anti-social behaviour."
