From BBC News:
Video at the link. When they say "stampede," they're not kidding. People were scattering across multiple blocks. Fortunately, no one was seriously injured.A man is due to appear in court after allegedly causing a stampede at a gay pride parade in the US which left seven people needing hospital treatment.
The man, named in US media as 38-year-old Aftabjit Singh, allegedly waved a BB gun, which fires small metal ball projectiles, in the capital Washington on Saturday.
A number of people reported hearing gunshots before the crowd fled.
However, officials maintain there is no evidence that shots were fired.
A police report - cited by the Associated Press news agency - said the man took the weapon out after noticing someone "hitting his significant other".
He has been charged with illegal possession of a BB gun, carrying a dangerous weapon and disorderly conduct. He is due in court on Monday.
Doesn't say how the guy was caught. Not sure if there was a dog pile, or if they figured out who he was after the fact.
