SAN FRANCISCO (CBS SF) — New video of the tour bus that plowed through a downtown San Francisco street and critically injured several people was released Wednesday.

The Union Square Business Improvement District provided the video, which shows the double-decker City Sightseeing bus careening down Post Street near Union Square on Friday afternoon.

Pedestrians can be seen jumping out of the way as the bus runs through street barricades and construction scaffolding.

About 20 people were hurt in the crash, with several in critical condition.

Three days after the crash, officials told KPIX 5 that the company that operated the bus has had numerous issues over the years.
