A woman who was injured in the 7 April terrorist truck attack in Stockholm died on Friday morning (28 April), raising the death toll to five.

The victim was identified as 66-year-old Marie Kide, a teacher and local politician who represented the Green Party in Trollhatten city council.

She had been hospitalised in southern Sweden after a stolen beer truck ploughed into a crowd of shoppers on a main pedestrian street in the Swedish capital.

"Marie leaves a huge void behind her, she was a woman with a big heart and courage in her convictions," Trollhattan Green Party spokesperson Esther O'Hara said.

"Marie, who was also the Green Party's representative on Trollhättan's education board, always stood up for kids and for the vulnerable in society. She spread warmth and love around her, and it was a privilege to work together with her. We miss her deeply."

Other fatalities from the attack were an 11-year-old Swedish girl, a 31-year-old Belgian woman, a 69-year-old Swedish woman, and a 41-year-old Briton identified as Chris Bevington, who worked in Stockholm as a director for music streaming service Spotify. Fourteen others were injured.

The main suspect, Rakhmat Akilov, a 39-year-old Uzbek man, was arrested in Marsta, a suburb north of Stockholm, several hours after the attack. He pleaded guilty to a terrorist crime days later during a court hearing where he was denied permission to change his lawyer to a Sunni Muslim.

Police say the father-of-four had expressed sympathy for Isis, but officers have not disclosed a motive for the attack and no extremist group has claimed responsibility.

In 2014 Akilov applied for a residence permit in Sweden, but last summer the application was rejected.

In February, police were instructed to deport him, but he allegedly went underground and eluded authorities' attempts to track him down.

The attack, which took place outside the upmarket Ahlens store, has shocked Sweden, which is known for its welcoming policy toward migrants and refugees.

In 2015, a record 163,000 asylum-seekers arrived in the country – the highest per-capita rate in Europe. The government has since curtailed some immigrant rights and tightened border controls, with 24,000 people deported last year.
