A bookstore chain canceled a series of Michael Vick book-signing events because of threats of violence against Vick and his family, multiple media outlets reported.
Vick was scheduled to sign copies of his book "Michael Vick: Finally Free" at Barnes and Noble stores in Atlanta, N.J., and Exton, Pa. Those appearances were canceled for safety reasons.
"This was a joint decision between Michael Vick's advisers and the publisher," said Vick family spokesman Chris Shigas, according to NBC 10 in Philadelphia. "They were canceled because of a recent uptick in credible threats of violence against Michael Vick, his family, the bookstores and the book store employees."
Shigas said multiple threats were made, including some that were posted on Vick's Facebook page.
There just seemed to be a collective, very few extremists who were noting the time and the place where these events would be," said Shigas. "They were working to gather support to commit acts of violence."
Police are investigating the threats.
Byron Williamson, the President of Worthy Publishing, which published Vick's book, told Philadelphia Magazine, "In football circles, Michael Vick's time as a federal inmate feels like ancient history. But for millions of Americans, Vick remains best known as the football player who went to jail for abusing dogs. We were reminded of this Monday, when the bookstore chain Barnes & Noble announced it was cancelling a series of Vick book-signing appearances due to threats of violence made toward the Philadelphia Eagles quarterback."
