Three people have died in a helicopter accident in California while filming shots for a Tv show.

The Bell 206B Jet Ranger crashed at the Polsa Rosa Movie Ranch near Acton in the early hours of Sunday morning (10Feb13).

The Los Angeles Film Commission claims that bosses at Tv company Bongo Productions had a permit to film in the area and were working on an untitled reality show at the time of the tragedy.

The National Transportation Safety Board and the Federal Aviation Administration officials are planning to launch an investigation.
