Reservations for Malaysia Airlines flight MH370 bought by two passengers using false passports in the names of Christian Kozel and Luigi Maraldi. “Now we have a real case where the world is speculating whether the stolen passport holders were terrorists, while Interpol is asking why only a handful of countries worldwide are taking care to make sure the persons possessing stolen passports are not boarding international flights,” Mr Noble said of the Malaysian flight. Malaysia’s prime minister Najib Razak has ordered an urgent review of his country’s air travel security procedures as investigators in Kuala Lumpur pour over CCTV footage of the passengers on flight 370 and question immigration officials and guards at the city’s international airport. “Every indicator shows some sort of security lapse, but I cannot say anything further right now,” said a security official with knowledge of the investigation. Investigators are trying to uncover the true identities of the passengers who used the stolen passports of Italian Luigi Maraldi, 37 and Austrian Christian Kozel whose passports were stolen on the Thai resort island of Phuket.

Can’t these immigration officials think? Italian and Austrian (passport holders) but with Asian faces?” he said. An Italian passport.

But Malaysian officials stress they have no evidence indicating what caused the plane to disappear during a red-eye flight from Kuala Lumpur to Beijing in the dark early hours of Saturday morning. Tickets bought by two passengers using false passports in the names of Christian Kozel and Luigi Maraldi. Flight booking information shows the passengers bought the tickets together at a travel agency in Pattaya, a seaside city outside Bangkok that is a known haunt of international criminal networks. They booked the flight to Beijing where they would not have had to clear customs before taking another flight from Beijing to Amsterdam. One, travelling under Maraldi’s name, was due to proceed to Copenhagen and the other to Frankfurt, Germany.

The men paid for the fares in Thai baht. The real Mr Maraldi was brought to a police press conference in Phuket where he is holidaying, telling how he reported his passport stolen on August 1 last year while on a previous holiday in Thailand. The passport went missing after he deposited it to rent a vehicle at a business in Patong, the red light tourist area on Phuket where hundreds of passports are lost or stolen every year. Mr Noble said some of Interpol’s 190 member countries cite a lack of police resources, privacy concerns or political hostilities with other countries for their failure to check passports against the global date base. Four of every 10 international passengers are not screened against the database, he said.

The database draws on information from 167 countries. In Thailand passport forgery and theft is a huge underground business. Last year police caught a Thai man with 5000 fake passports. Forgers are using advanced technology to make fake passports. Thai police general Warawuth Thaweechaikam said: “it must take great skills and expertise by our officers to detect the fake passports and visa stamps because the system cannot detect them the whole,” he said.

Mr Najib, the prime minister, said security at Malaysia’s airports would be improved after the review but stressed the cause of the plane’s disappearance remains inconclusive. Australian airlines “We need to look at all the possible leads before reaching a conclusion…we still do not know what really happened and have yet to obtain any substantial leads,” he said. Qantas said it could not detail whether its passengers were checked against Interpol’s Stolen and Lost Travel Documents database, citing security and confidentiality restrictions. “Qantas works closely with law enforcement agencies in Australia and overseas, but for security reasons we cannot disclose the detail of those arrangements,” a spokesman said.

Virgin Australia referred the matter to the Australian Customs and Border Protection. Customs and the Department of Immigration and Border Protection Service have been contacted for comment. The US searches the database annually more than 250 million times; the UK more than 120 million times; and the United Arab Emirates more than 50 million times. Interpol has been contacted for comment about how many times Australia has accessed the databases. Immigration and Border Protection Minister Scott Morrison said Australian officials had access to international lists for stolen passports and that a check was done when people left Australia.

He told Macquarie Radio on Monday that Australia was seeking to work with other countries in the region to strengthen their systems. ‘‘I’ve always said if we have stronger borders in the region we have stronger borders in Australia as well.’’ Mr Morrison said people stole passports for a variety of reasons including smuggling and other criminal purposes. ‘‘Who knows what purpose has been in place on this occasion.’’ Loading

He said the issue was one reason authorities should go towards microchip passports which had biodata in them to improve the level of checks. with Megan Levy, AP
