[3] The only injured person was the one-legged Chechnyan-Belgian[2] bomber Lors Doukaiev, who was caught in a nearby park, Ørstedsparken, following the explosion, but only identified several days later.

[5] Considering that the bomber bought a bus ticket to Belgium with departure from Denmark on 10 September,[6] and he was seen at a post office buying a small box used for mailing CDs, as well as a roll of tape,[6] it is believed that it was not meant to be a suicide attack against the hostel, but rather an accident while making a letter bomb, which happened as a consequence of Doukaiev's use of a highly volatile explosive substance.

[7] The Danish police revealed a hypothesis regarding the purpose of the bomb.

According to the police hypothesis, Lors Doukaiev constructed a letter bomb, which was meant to explode upon opening.

[7] Despite Lors Doukaiev's continued claims of innocence, a unanimous panel of judges found him guilty of attempted terrorism,[8] and on 31 May 2011 he was sentenced to 12 years in prison.
