Early Wednesday, the Police in northern Italy arrested three people after the investigation on the cable car crash showed that a clamp, intentionally placed on the brake as a patchwork repair, prevented the brake from engaging after the lead cable snapped.

Carabinieri Lt. Col. Alberto Cicognani three people had been questioned overnight and one of them admitted to what happened. 

 He said the fork-shaped clamp had been placed on the brake specifically to prevent it from engaging because it was braking spontaneously and preventing the funicular from working.

The clamp was put several weeks ago as a temporary fix to prevent further interruptions in the funicular service, Cicognani said.

The lone survivor, a 5-year-old Israeli boy whose parents, brother, and two great-grandparents were killed, remains hospitalized.
