MADISON, Wis. -

Madison police said the number of robberies reported in 2013 went up after years of decline. 

Capt. Joe Balles said robberies reported in 2012 were just under 250, but last year reports were up to 302. 

Balles said two factors could be contributing to the 21-percent increase, including a spike in thefts of smartphones, also called "Apple-picking," a nickname stemming from the maker of the popular iPhone. 

A rash of home invasions in the Greenbush and Vilas neighborhoods in the fall added to the spike, Balles said. 

Kendredge Dillard, 21, was arrested on suspicion of armed robbery in October in connection to thefts of electronics, wallets and phones. 

Robberies had been at a high in Madison seven years ago, reaching at 438 reports in 2006, police said.
