Police in Reykjavik have arrested three people at an Asian restaurant after one of them tried to escape through a back entrance, police said. The arrests took place on Thursday at the restaurant on Geirsgata in the Icelandic capital. Officers are also assessing whether two of the suspects should be removed from the country, a decision that falls to the Directorate of Immigration. The third person has stronger ties and is not subject to the same review. Police said the three were working as guides without the required permits. They were allegedly acting like licensed tour leaders while a group of foreign visitors was at the restaurant. The escape attempt happened as officers moved in. A police spokesman said the suspect did not get far. The restaurant was not placed under a special investigation. The person responsible for the venue was called in for questioning but was not arrested. Police said the suspects all have residence permits in Europe, but they had not been authorized to work as guides. The spokesman said authorities have increased their attention to people operating as tour guides without permission, and that similar cases have been reported recently. The case remains under review as immigration authorities consider whether two of the suspects should be sent out of the country.
