Man convicted of threatening Yahoo CEO Marissa Mayer now accused of stalking her via email

AUSTIN, Texas – A man convicted of threatening Yahoo CEO Marissa Mayer is now accused of sending her dozens of sexually graphic emails.

Austin police say 30-year-old Gregory Calvin King was arrested Thursday, a month after he was released from a federal prison in Texas. He’s jailed on $100,000 bond on a charge of stalking with a previous conviction.

King was arrested in 2011 for threatening Mayer, then Google’s vice-president, after repeatedly calling her and sending her more than 20,000 Twitter messages.

Court records show he was sentenced to supervised release, but later violated his probation and was sentenced to a year in prison. He was released last month and had been under surveillance by Yahoo since arriving in Austin.

Court records don’t list his attorney. Yahoo declined comment Friday.
