Officers said the rapper told the man some encouraging words, which allowed the situation to end peacefully.
Police said it doesn't appear the two men knew each other. /*T.I.*/ was just happy he could help save the man's life.
"With the help of the negotiators and them allowing me to help, we sent him a message. I let him know that I was here and I was willing to help him, and he came down peacefully and everything was resolved," said the rapper.
T.I. is due in court Friday for a parole hearing after being arrested on suspicion of drug offenses in September in /*Los Angeles*/.
He is on supervised release after spending a year in prison on federal weapons charges.
