Contractor was trapped for 11 hours under fallen masonry at medieval landmark near the Colosseum

Prosecutors have opened a manslaughter investigation over the death of a worker trapped when a medieval monument in central Rome partly collapsed.

Octav Stroici, 66, was rescued on Monday night after 11 hours under fallen masonry but died of his injuries at the city’s Umberto I hospital. Romanian foreign affairs officials, who said he came from their country, thanked rescuers for their efforts to save him during a long, complex and delicate operation.
