Workers injured, trapped, in collapse at demolition site at old South Boston power plant

WCVB reports one worker was seriously injured and two others also hurt during demolition work at the former L Street Boston Edison plant, being mostly torn down to make way for a mixed-use development. The most critically injured person remains trapped in rubble at the site.

It's the second collapse at a Boston demolition site this year. In March, a worker died at the old Government Center Garage.
