NEW YORK (CNNMoney.com) -- Omaha police are investigating an attempted robbery at Warren Buffett's home, CNNMoney learned Thursday.

According to Negron, Buffett's wife Astrid had seen a man at the door and rang the security guard.
She told 911 that the man showed what appeared to be a gun to the security guard, and the two struggled with each other. The man hit the security guard in the head with the blunt weapon, but the guard was able to take the object from him, said Negron. The gun was later determined not to be real.
Warren Buffett was at home at the time of the incident.
The suspect is described as white, dressed in dark clothing, a dark stocking cap, a dark baseball cap and with dark camouflage paint on his face. Officers estimate he is 24 to 26 years old, and about 5 feet 10 inches tall.
He is still at large.
