Bay Area rapper Mac Dre's tombstone was stolen from his grave at Oakland's Mountain ViewCemetery this past weekend.

Dre's longtime friend/collaborator AP confirmed the horrendous act to SOHH.com.

"My agent called me and told me," said AP . "My peoples talked to Dre's momma. That's the best source you can get."

The Oakland rapper is now offering a $10,000 reward for anyone who comes forward with information leading to the offender.

"I got 10,000 for whoever bring me the motherfucker that did it," fumed AP. "I got 10,000 to beat somebody ass. If somebody knows what's up, I don't give a fuck who it is. Not because it's Mac Dre. I don't give a shit if it was Joe Blow, you just don't do that type of shit. Let him rest in peace.

"You fucking with dead motherfuckers," he continued. "Niggas done already killed my nigga -- now he's dead. You still messing with the dead, man? I'ma hold it down for Mac Dre if nobody else ain't gon do it, I'm gon hold it down."

Dre (born Andre Hicks) was killed in a drive-by shooting Kansas City's U.S. 71 highway while he was being driven back to his hotel in November 2004.

The murder was followed by the murder of Kansas City rapper Fat Tone. The following months saw the two cities engage in a bloody feud that produced several casualties, including Fat Tone's aunt, rapper < STRONG>Jermaine "Maintain" Hughes and the death of a fan who was killed during a Dre memorial in San Francisco last year.

However, AP, who now resides in Las Vegas, doesn't think Kansas City had anything to do with the stolen tombstone.

"Hell nah, man," said AP . "They not that stupid. They ain't gon do nothing like that. I don't think it's no niggas or nothing like that. I think it's some white fan -- motherfuckers shroomed-out. I don't think that it's anybody that we would associate ourselves with. It's more like a fan.

"We got love for Kansas City," added AP. "We just hate what happened to Dre. Everything is cool. To tell you the truth, ain't none of my niggas going to Kansas City, cause I don't want nothing to happen to nobody. There's somebody out there that really wanna earn a stripe or something. It ain't cool to go out there. We ain't doing no shows or nothing. Since Dre got killed, no Bay area rapper has done no shows in Kansas City."
