LIVERMORE, Calif. (AP) - Police in Northern California say a cousin of rapper MC Hammer has been accused of raping a woman he met on the social networking site Twitter.

KPIX-TV reports that 33-year-old Marvin Grant was arrested Thursday in the sexual assault of a 40-year-old woman who arranged to meet him at a Livermore hotel Wednesday night. He faces one charge of rape.

Livermore Police Lt. Matt Sarsfield says the two developed a romantic relationship over e-mails and phone calls.

Police say Grant attacked the woman after she declined his advances.

Grant, who is also known as Marv, appears on the rapper's reality show on the A&E cable network. The show follows the rapper and his family at his Tracy home.

It wasn't immediately whether Grant had a lawyer.
