One thief had a change of heart after he discovered that the victim he attacked and robbed had Asperger's, according to the Daily Mail

Connor Dawes, 19, knocked down a young man in an alleyway near Warwick Crown Court in Warwickshire, England. He then stole the man's phone and wallet and kicked him before taking off, according to the Daily Mail. After he took off, Dawes went through the wallet and discovered that the victim had Asperger's, so he turned himself into the police, according to the 2014 Daily Mail story. 
Dawes of Nottingham told court officials that he and a friend were walking when they spotted the victim. Security footage obtained by the police showed Dawes following the man for a few minutes before knocking him to the ground, pulling off his coat and stealing his phone and wallet, according to the Daily Mail. 

The unnamed victim cut his eye in the fall and had a difficult time moving on from the incident, according to the Nottingham Post. 

Asperger syndrome is a form of high-functioning autism. While individuals with Asperger's may have higher-than-average IQ scores, they typically display deficits in social and communication skills. Many people often see them as naive, according to ASPEN.  

Despite turning himself in and calling himself "scum," Dawes was sentenced to two years in prison. 

"You may not have known this young man had Asperger's, but you certainly knew he was vulnerable because he was on his own at night, and there were two of you and only one of him. ... I have two boys to consider; not just you, but the boy you attacked and robbed. The message has to go out that people who do that go to prison," Judge Sylvia de Bertodano said at the hearing, according to the Nottingham Post.
