A former US Navy SEAL who wrote a book about the daring operation on Osama Bin Laden’s compound in Pakistan has agreed to forfeit $6.8 million in book royalties and speaking fees, the New York Times reported on Friday, citing federal court documents.

Matt Bissonnette, who wrote the book under the pseudonym ‘Mark Owen,’ also apologized in a statement for not getting the book vetted by the Pentagon before it was published in 2012, the New York Times said.

‘I accept responsibility for failing to submit the book for review and apologise sincerely for my oversight,’ the newspaper reported the statement as saying.

In the past the Pentagon has threatened legal action against Bissonnette for alleged violation of non-disclosure agreements because the manuscript was not submitted for a pre-publication security review.

The Department of Justice could not immediately be reached for comment.
