The incident occurred on July 12, the first day of the family's holiday at the King Evelthon Beach Hotel and Resort in Chlorakas, near Paphos. Foster, his wife, two children and in-laws had arrived in Cyprus in the early hours of that day and spent time at the pool before preparing for dinner.
At about 18:00, Foster, his father-in-law and his son walked toward an elevator. According to the father's lawyer, Alexandros Alexandrou, Foster was in a "good mood" and playing with his son. He lifted the child to show him the view from a window on the fourth floor but lost control, and the boy fell approximately 40 feet (12.1 metres).
Following the sentencing on Friday, Foster told reporters: "Thank you for the support. I'm looking forward to going home and being with my wife and daughter."
The court had earlier heard that Foster, an auditor, had believed the window was closed when he put his son on the sill. The boy died at the scene.
