Kvitova, now on top of her game, seems to have identified attacker

"I'm pretty happy that I think those people are already looking to me as Petra, as a tennis player," Kvitova said this week in an interview with ESPN The Magazine, having recently re-entered the Top 10 and won her third title of the season.

The 28-year-old Czech found herself in the news for completely different and unwanted reasons in 2016, when she experienced a knife attack in her home in the Czech Republic that left her playing hand badly damaged. A year ago, she was just starting her comeback, having required hours of surgery and weeks of rehab just to allow her to again hold a racquet.

"When the attack happened, obviously it was big. It was on TV and in newspapers everywhere, and it's like a movie from Hollywood," she said. "Lying in the bed in the hospital and seeing it in the news felt pretty weird."

Kvitova described the effects of the attack as "very tough" and said she still hoped her attacker would be found. "I do have flashbacks and thoughts on it, but it's better," she said.

Now, it appears an alleged suspect has been arrested by Czech police, according to Czech television. Police have not confirmed the account.

It said that police, who had stopped actively investigating the case, received a tip at the beginning of the year that led to the arrest. It also indicated that Kvitova has seemingly identified the perpetrator.

That would be another significant step in just getting back to being a tennis player.
