The British star flew into Tel Aviv last week to play a series of charity gigs to raise funds to help rebuild the troubled area around the Gaza Strip, but his travels were marred by his experiences immediately after landing in the city.

According to NME.com, Lowkey had his U.K. passport confiscated and was questioned and detained for nine hours before being released.

He tells the website, "As soon as I stepped off the plane with my guide to Israel tucked under my arm, I was pulled away to the side and interrogated as to why I was in Israel, by a man who wore no uniform identifying himself as any type of security but was clearly heavily armed.

"After this I carried on through to passport control. After giving over my British passport it was confiscated. I was then detained for nine hours. During this time I was interrogated about many aspects of my life, what the purpose of my trip was, where my parents are from and where I planned to go in Israel.

"Eventually I was told my story was a lie and was subjected to a bout of the Israeli polices paranoid mind games. I was eventually released, knowing that no matter how frustrating what I just went through was, I knew that it was not even a miniscule fraction of the degradation Palestinian people are subjected to on a daily basis."
