Some 5,198 foreign citizens were expelled from the country in 2013, an increase of 31 percent since 2012, when 3,958 people were deported.
"It is the highest number we've had ever," Frode Forfang, head of the Directorate of Immigration (UDI), told NRK. "We believe that one reason for the increase is that the police have become more conscious of using deportation as a tool to fight crime."
Nigerian citizens topped the list of those expelled for committing crimes, with 232 citizens expelled as a punishment in 2013, followed by Afghan citizens with 136 expelled as a punishment, and 76 Moroccans expelled as a punishment.
