Uzbek man main suspect in Swedish truck attack that killed four

By Johan Sennero, Anna Ringstrom and Bjorn Rundstrom STOCKHOLM (Reuters) - A 39-year-old Uzbek man being held in custody is the suspected driver of a hijacked beer delivery truck that plowed into crowds in central Stockholm, killing four people and wounding 15 in an apparent terror attack, police said on Saturday. The man, previously known to Swedish intelligence services as a marginal figure with no clear links to extremist groups, is suspected of mowing down pedestrians on a busy shopping street and smashing through a store front on Friday. "Nothing indicates that we have the wrong person, on the contrary, suspicions have strengthened as the investigation has progressed," Dan Eliasson, head of Sweden's national police, told a news conference on Saturday.
