No good deed goes unpunished. Despite being a good Samaritan and helping prevent an attempted suicide yesterday, T.I. is now being faced with critics who question his motives.

The Got Your Back hitmaker rushed to the scene upon hearing that a man was threatening to leap to his death from the top of a 22-story building in downtown Atlanta on Wednesday (Oct. 13). He made a detour on the way to a video shoot and offered to help the cops, persuading the man to come down using a heartfelt video message.

Tip, who has a court hearing scheduled Friday for his recent arrest on drug possession, said he was not motivated by his personal interests. For one, Im not taking any credit, he told V103s Ryan Cameron. I didnt do it I couldve just as well came down there and it could have been resolved in another way. The fact of the matter is that God put me in a position to help, and I cant take any credit for that.

I didnt wake up this morning with the intentions of going down and helping hostage negotiators talk someone down off of a ledge. I dont think that could be in anyones plan of action. If not me, then who? If not now, then when? Sometimes life happens certain ways.

Atlanta officer James Polite vouched for Tip. He didnt have to stop. He couldve kept on going about his business, he told The Atlanta Journal-Constitution. Were happy it ended the way it did, and we thank him.

The rapper also delivered a message to his supporters who have been disappointed by his repeat run-ins with the law. All of those who have been let down by these circumstances, I want to give you my sincerest apologies and let you know that I will make it up to you and make you proud in the future.

T.I. played a key role in talking a suicidal man off the ledge of a 22-story building in Atlanta today ... TMZ has learned.

It all went down earlier this afternoon -- when cops responded to a 911 call about a man who was threatening to jump off a building in downtown Atlanta ... the same building where Ryan Cameron's Radio Show on V103 is based.

We're told T.I. heard about the jumper on the radio -- and called Ryan Cameron to see if there was anything he could do to help out with the situation.

Ryan Cameron tells us ... he told T.I. to roll over to the building, where the rapper met with police and recorded a heartfelt video message which cops then played for the man on the roof.

We're told after the man saw T.I.'s video he agreed to step off the ledge ... and met T.I. in the lobby, where the two were able to talk things out.

Ryan Cameron also tells us that cops informed the radio station that they will not be pressing charges against the man.

Calls to T.I.'s reps have not been returned.
