The Metropolitan Transportation Authority says it's conducting safety inspections at its construction sites after a crane collapse killed a worker in New York City.

The accident happened Tuesday night in Manhattan, where the MTA is building an extension of the No. 7 subway line.

The MTA says it has suspended all work at the site until further notice. It has also ordered the inspection of all cranes at MTA construction sites in the city.

Police identified the killed worker as 30-year-old Michael Simermeyer, of Burlington, N.J.

Crane safety came under close scrutiny in New York in 2008, when nine people were killed in two separate collapses in Manhattan. The owner of one of those cranes is standing trial on manslaughter charges.
