The front page of a UK newspaper report that said Captain Zaharie Ahmad Shah, who piloted MH370, was affected by opposition leader Anwar Ibrahim's sodomy trial.

Family and friends say there is nothing in their personalities or past to suggest they would have committed foul play.

"I've never seen him lose his temper. It's difficult to believe any of the speculation made against him," said Chong, a friend of Zaharie, describing him as highly disciplined and conscientious.

International media scrutiny and investigations by the Malaysian police have failed to turn up red flags on either the captain, 53-year-old Zaharie, or the co-pilot, 27-year old Fariq Abdul Hamid.

Captain Shah joined the carrier in 1981 and has 18,365 hours of flight experience.

CCTV footage, supposedly of the pilot and co-pilot going through security checks at the KL International Airport (KLIA) prior to boarding the Malaysia Airlines MH370 flight, has found its way onto the Internet.

British tabloid Daily Mail uploaded a CCTV recording of Captain Zaharie Ahmad Shah and first officer Fariq Abdul Hamid on their website

which showed the two being frisked as they passed a security checkpoint at the boarding gate in KLIA before the flight from Kuala Lumpur to Beijing on March 8.

This, coupled with the fact the plane's communication equipment was disabled before the exchange took place "suggested an attempt to mislead ground control", and added to "suspicions that someone who knew the controls was involved in the disappearance".

Captain Shah's colleagues described him as a jovial but professional "aviation geek" who collects remote controlled miniature aircrafts, light twin engine helicopters and amphibious aircrafts.

It was unclear if they took away a flight simulator from his house. The media was barred from entering the housing area by security guards.

Police searched the home of Captain Zaharie Ahmad Shah of the missing Malaysia Airlines flight last Saturday.

The search of the pilot's home began when Malaysia acknowledged that the Beijing-bound plane had been diverted deliberately by a person or persons with expert aviation knowledge.

Three policemen in an MPV showed up at a posh gated community at Section 13 around 2.40pm and left around 4.45pm.

The search came soon after Prime Minister Datuk Seri Najib Tun Razak confirmed that the plane was suspected to have been deliberately diverted.

First Officer Fariq Abdul Hamid, 27, who along with a fellow pilot violated airline rules in 2011 by allowing two young South African women into their cockpit during a flight, one of the women told Sydney-based Nine Network.

The report included photos of the women in the cockpit, with one appearing to show them posing with a man resembling Fariq.

Passengers have been prohibited from entering the cockpit during a flight after the 9/11 attacks on the United States.

The encounter took place during the one-hour flight from the Thai beach resort of Phuket to Kuala Lumpur, Malaysia's capital, the report said.

"Malaysia Airlines has become aware of the allegations being made against First Officer Fariq Abdul Hamid which we take very seriously. We are shocked by these allegations," a statement by the airline said.

"We have not been able to confirm the validity of the pictures and videos of the alleged incident. As you are aware, we are in the midst of a crisis, and we do not want our attention to be diverted," the airline said.
