and Uvalde, Texas
Osaka, who was at the event, said she was “petrified” when she saw the commotion.
“I was just in the Barclays center and suddenly I heard shouting and saw people running, then we were being yelled at that there was an active shooter and we had to huddle in a room and close the doors,” Osaka said on Twitter
In a later statement
, the four-time tennis grand slam champion said: “I was lucky enough to have a security guard with me and I cannot imagine having to navigate through that situation by yourself, let alone being a child and it not being a false alarm.”
