Wikipedia says robbery, assault and sexual assault ("contact crimes") together made up 12% of reported crimes in 2003 Sweden. Theft related were 53%.
The article claims that in 2007 Sweden "violent crimes and robberies make up about 75 percent of all crimes reported in Sweden."
I'd say they've conflated theft and robbery in that article, possibly a translation issue, possibly fear mongering.
(edit: and this is backed up by the link to the official stats given elsewhere in the thread by
Xylakant which has robbery as less than 1% of reported crimes in 2012)
