The suspect was brought in just hours after police put out an appeal for help in the media, newspaper Aftenposten reports.

”Tips from members of the public enabled us to arrest a man charged with assault. Furthermore, we’re now looking for another man who has been named,” said Shahin Manjothir at the Grønland police station.

The brutal assault took place on a pedestrian bridge between Oslo’s central train station and bus terminal at around 1pm on June 6th.

In an apparently unprovoked attack, the main assailant kicked the woman so hard that she fell out of her wheelchair and was knocked unconscious.

”We don’t know what was behind the attack and want to get answers on whether it may have been racially motivated,” said Manjothir.

On Wednesday, police released surveillance footage showing the primary suspect wearing a black jacket with the initials SATS on the back. The other man was wearing a yellow jacket and accompanied the alleged aggressor before, during and after the attack.

Both men have what police described as a Nordic appearance. The man in the black jacket is around 180cm tall and appears to have a muscular physique, police said. The second man is around the same height and has a sturdy build.

Oslo police have asked anybody who may have witnessed the attack, or may have information about the suspects, to contact them at: 22 66 99 66.
