The Home Ministry on Friday formed a nine-member probe committee to look into Monday's incident in which a man sneaked through three layers of security and boarded an aircraft parked on the tarmac of Tribhuvan International Airport without any documents.

As the country’s sole international airport is heavily guarded by the Nepal Army, Armed Police Force and Nepal Police, Monday’s incident has left everyone wondering how the man managed to breach the three layers of security to reach the sensitive no-go zone.

The man was arrested and police have identified him as Haspam Alam of Rautahat.

The Home Ministry formed the committee four days after the incident.

The committee, headed by Narayan Prasad Bhattarai, director general of the Immigration Department, has been given seven days to submit a report.

In the past years too, many reports have pointed out that there are many vulnerable loopholes in the airport’s no-go or sterile area due to management problems.

Airport officials described the incident as glaring.

According to Nepal Airlines, on February 21 night, Alam was found seated in the business class of an Airbus A330 plane, registration number 9N-ALY, which was preparing to fly to Doha.

After the incident, Nepal Airlines suspended Dhruvaraj Thapa, security commander of Nepal Airlines.

Officials say what exactly happened could be revealed only after the committee submits its report.

Senior Superintendent Bhim Dhakal, the chief of Kathmandu’s airport, said that there was no fault from the Nepal Police side.

A preliminary report of the police said that Alam used to enter the no-go zone through the fence from the south side or Koteshwor side of the airport.

What has left security officials perplexed is this is the second such incident at Kathmandu's airport in less than a month by the same person in the same fashion.

Alam was set free in the first incident after police said he was mentally challenged, according to airport officials.

The Post could not independently verify the intent of Alam repeatedly breaching airport security.

“Alam is currently at the Metropolitan Police Circle, Gaushala,” said Dhakal. “Investigation is underway.”

Airport officials say security agencies’ failure resulted in the incident.

At least three Nepal Airlines officials told the Post that Nepal Airlines is only a service provider and that airport security does not fall within its scope of responsibility.

“There are three layers of security,” said a Nepal Airlines official who did not wish to be named.
