Berlin police said crime increased by 11.5 percent in the last year with the number of people being pick-pocketed going up from 4,910 to 5,850.
And crime on the city's U-Bahn and trains rockets on weekend nights, the Berliner Morgenpost newspaper reported.
Police spokesman Meik Gauer said the thieves targeted a certain type of victim.
“Most of these incidents take place at the weekend when people are drunk at night after visiting clubs and get the train and are helpless because of the alcohol," he said.
Thieves often cut open passengers' bags and pockets with razor blades or Stanley knives, he added.
Gauer said: “A lot of the time the victim is unconsciously helping the thief when, for example, they wear headphones. The criminal then just has to follow the cable to the iPhone.”
