The man who attacked two-time Wimbledon champion Petra Kvitova with a knife at her Czech home in December 2016 was sentenced to eight years in prison on Tuesday, a court said.

"He got eight years in a tight-security prison," Eva Angyalossy, a spokeswoman for the regional court in the southern Czech city of Brno, told AFP. The 33-year-old Radim Zondra, who is currently in prison for another crime, was sentenced on charges of serious battery and an illegal entry into Kvitova's flat. Angyalossy said that Zondra and the prosecutor had two weeks to appeal the verdict. Zondra pleaded not guilty.
