MC Hammer had a run-in with the law recently.  And he's putting the police department on blast via Twitter for racially profiling him and wrongfully citing him.

Deets inside....

Thursday, when Hammer was driving in Dublin, CA after putting in some community service helping out the inmates who are turning their lives around in San Quentin, he was arrested for Obstruction of a police officer.

Here's what went down, according to the Oakland News, the 50-year-old rapper was booked at the Santa Rita jail after an officer approached him at a local shopping center.  And a verbal altercation reportedly occurred.

Last night, Hammer gave his side of the story and claims it was simply racially profiling and he did nothing wrong (read from the bottom up):

Not far-fetched at all.

Hammer also posted this pic below:

He said, "Disappointment? I was on my way to San Quentin Friday morning to congratulate a group of inmates in "The Last Mile".

And he ended his statement saying, "Instead of being bitter, I'm taking the opportunity to make this a "teachable moment" and "eye opener" for my many friends & colleagues."

Please Hammer don't hurt 'em!
