This apparently was just the worse of the rapes. From the same article:

Last month, a Pakistani was arrested after breaking into the home of a 65-year-old Greek woman with the intent to rob her but ended up allegedly raping her.

Just days earlier, a 34-year-old Pakistani man was arrested after being accused of attempting to rape several underage girls in the southern suburbs of Athens. The man was caught after one victim filmed him on her mobile phone and posted the video on social media to identify him.
