Italy has sent experts to help Venezuelan authorities search for a plane that disappeared carrying the CEO of Italian fashion firm Missoni.

More than 400 people in boats, planes and helicopters were searching for the twin-engine aircraft, which disappeared off the resort islands of Los Roques.

The BN-2 Islander disappeared on Jan 4. It dropped off radar about 11 miles (18 kilometers) south of Los Roques during a flight to Caracas.

It was carrying two crew members and four Italian tourists, including Vittorio Missoni, CEO of his family's fashion company.

Venezuela's government announced on Thursday that four Italian experts have joined the search.
