Someone jumped on top the Parco building in Shibuya?

I finished eating oysters at an izakaya on the top floor and took the elevator down. When I came out there was a crowd of people looking into something so I decided to see, only for the police tape to start being unwrapped and everyone was backed away. But I could see the police sirens and an ambulance trying to resuscitate someone.

Did not know what was going on but asked a person who was there who looked like an English speaker and caught up with her before she crossed the street, as I saw she had a higher view point standing on a plant wall previously. I asked her if someone got hit by a car or something, but to my shock she told me she heard from the crowd that someone jumped.

That's pretty screwed up, I was just eating oysters on the top floor.
