The suspect for the truck attack in Stockholm that killed four people on Friday is a rejected asylum-seeker from Uzbekistan who had been running from authorities for more than a month, police said Sunday.
The suspect, who has only been officially identified as a 39-year-old man from Uzbekistan, "applied for a permanent residency permit in 2014", Police chief Jonas Hysing Hysing said.
Police commander Jonas Hysing told the paper "we do not know where they are, so we cannot enforce expulsion", speaking of the many migrants who should be deported from the country but the government keeps no records of their whereabouts.
