The father of Dylann Roof, the man accused of killing nine black people in a Charleston church, claims to have received threatening calls and to be in fear for his life.

Franklin Roof called police to his home in Columbia, South Carolina, according to police records obtained by the New York Daily News.

"The victim states that individuals claiming to be with the Black Panther Party have called several times and left messages stating, 'I'm coming to see you real soon, buddy boy,'" records say.

"The victim states that another individual claiming to be from the Nation of Islam called and stated that they wanted to interview him and make sure his whole family was there. The victim states he believes that these phone calls are implied threats."

On Friday, Franklin released a statement expressing "shock, grief, and disbelief" after his son was arrested for the attack at a bible study group in Emanuel AME Church in Charleston.

"The victim states that whenever his phone is turned on, that he is constantly receiving calls from restricted numbers that are making harassing comments with implied threats to harm, with the intent to intimidate him and his family," police records say.

"He has to keep his cellphone turned off in order to stop the calls from coming in. The victim is concerned for his safety as well as his family safety."

There is currently a police guard outside Franklin's property, reported the newspaper.

In court documents obtained by the Daily Mail, Franklin's ex-wife Paige Mann accused him of domestic violence.

The news comes as a document believed to be Roof's manifesto surfaced online.

In the 2,500 word document entitled The Last Rhodesian he describes his racist views, and includes pictures of himself holding a gun and wearing a jacket with flags of Rhodesia and Apartheid-era South Africa.
