Rocker Henry Rollins is under investigation by the Australian government after he was spotted reading AHMED RASHID's bestselling book JIHAD: THE RISE OF MILITANT ISLAM IN CENTRAL ASIA on a recent flight to Brisbane, Australia.

The former Black Flag frontman, 45, was horrified when he received an email from an Australian government associate, after an ignorant passenger reported the singer/actor's reading material.

Rollins tells, "Days later I received an email from a woman who I guess figured out who I was and found me. I had been named a 'person of interest'.

"Basically, they get calls like this every five minutes, and I'm probably on the 'who cares' list, in that they'll probably let me into the country again.

"But the fact that this guy could be that ignorant and call me in on this for a book. I was angry. Because of the fact that the guy wouldn't confront me. I like confrontation. If I've offended you, let me know. Don't call it in and not leave your name. I just think it's pretty weak."

Rollins was especially baffled by his status amongst Australian immigration officials, because of his past track record working with US soldiers.

He explains, "I do a lot of work for the USO because soldiers are my heroes. I've done six USO tours outside of America and a few hospital visits, and the soldiers are the best. I've been to Iraq, Afghanistan, Kuwait, Dubai, South Korea, Honduras, Japan, Egypt and Turkey."
