At 3am on 8 June 2005 her car, parked in a garage alongside her house, was set on fire. The car and a side of the house were burned, but Hvilshøj, her husband, and her two small children escaped unharmed. As of 2008[update] no arrests had been made, and it is not known who started the fire;[2] a young man seen running away from the house was identified by police, who said he was not under suspicion.[3]
An unknown group calling itself "Aktionsgruppen Grænseløse Beate", The Actiongroup Borderless Beate ("Beate" is a name) sent an email claiming responsibility, citing what it called the government's "racist refugee politics" as the reason for the attack. The police say that the email was composed the day before the attack, on a Yahoo! Mail account in the Internet cafe Powerplay on Østerbro, Copenhagen.
At one point the police announced that they had the person who had composed the email in custody. However, the man was found to have an alibi documenting that he could not have been at the internet cafe at the indicated time.[4] It was later reported that the employees who had pointed out the man had lied to cover internal affairs in the cafe, which they did not want the police to see (the news article is not explicit, but implies that the internal affairs they tried to hide are unrelated to the arson attack). The two men who lied were charged with making false witness statements, an imprisonable offence.[5]
