We were invited to Qatar by the prime minister's office to see new flagship accommodation for low-paid migrant workers - but while gathering additional material for our report, we ended up being thrown into prison for doing our jobs.
Our arrest was dramatic.
We were on a quiet stretch of road in the capital, Doha, on our way to film a group of workers from Nepal.
The working and housing conditions of migrant workers constructing new buildings in Qatar ahead of the World Cup have been heavily criticised and we wanted to see them for ourselves.
Suddenly, eight white cars surrounded our vehicle and directed us on to a side road at speed.
A dozen security officers frisked us in the street, shouting at us when we tried to talk. They took away our equipment and hard drives and drove us to their headquarters.
Later, in the city's main police station, the cameraman, translator, driver and I were interrogated separately by intelligence officers. The questioning was hostile.
We were never accused of anything directly, instead they asked over and over what we had done and who we had met.

During a pause in proceedings, one officer whispered that I couldn't make a phone call to let people know where we were. He explained that our detention was being dealt with as a matter of national security.
An hour into my grilling, one of the interrogators brought out a paper folder of photographs which proved they had been trailing me in cars and on foot for two days since the moment I'd arrived.
I was shown pictures of myself and the team standing in the street, at a coffee shop, on board a bus and even lying next to a swimming pool with friends. It was a shock. I had never suspected I was being tailed.
At 01:00, we were taken to the local prison.


It was meant to be the first day of our PR tour but instead we were later handcuffed and taken to be questioned for a second time, at the department of public prosecutions.
Thirteen hours of waiting around and questioning later, one of the interrogators snapped. "This is not Disneyland," he barked. "You can't stick your camera anywhere."
It was as if he felt we were treating his country like something to be gawped at, suggesting we thought of trips to see controversial housing and working conditions as a form of entertainment.
In perfect English and with more than a touch of malice, he threatened us with another four days in prison - to teach us a lesson.
I began my second night in prison on a disgusting soiled mattress. At least we did not go hungry, as we had the previous day. One of the guards took pity on us and sent out for roast chicken with rice.
In the early hours of the next morning, just as suddenly as we were arrested, we were released.

Bizarrely, we were allowed to join the organised press trip for which we had come.
It was as if nothing had happened, despite the fact that our kit was still impounded, and we were banned from leaving the country.
I can only report on what has happened now that our travel ban has been lifted.
No charges were brought, but our belongings have still not been returned.
So why does Qatar welcome members of the international media while at the same time imprisoning them?
Is it a case of the left arm not knowing what the right arm is doing, or is it an internal struggle for control between modernisers and conservatives?
