EAST POINT, Ga. -- A veteran detective calls it one of the dumbest mistakes he's ever seen. Now that mistake has put a suspected bank robber in jail.

East Point police said they easily arrested a robbery suspect because he had a cab pick him up and take him to the bank. Officers said they simply returned to the address and arrested him there.

"I've been a police officer for 18 years and this is one of the dumbest acts I've ever seen," said Capt. Russell Popham with the East Point Police Department.

Popham said he and other officers were able to pick up Marcus Chisholm at the Camp Creek Parkway apartment where he lived in large part because just an hour and 15 minutes earlier Chisholm had a cab pick him up at the same address and take him to a SunTrust Bank which, Popham said, Chisholm then robbed.

"A male subject had entered the bank and produced a note to the teller and the note said if she didn't give him the money that he was going to kill her," said Popham. "When he presented the note he had his finger in his jacket pocket as if he had a gun."

Officials said the teller cooperated and gave him money.

Popham said after Chisholm got the cash he got back in the cab. Witnesses spotted the taxi and told East Point police the name of the cab company.

"We learned what taxi cab company it was and contacted them, had the cab driver come back and give an interview," said Popham. Officials said the cab driver returned to the scene and identified the man seen in the bank surveillance video as his passenger. The cab driver then gave authorities the address where he'd picked the man up.

"The cab driver did not have any idea that he had just taken someone to commit a bank robbery," said Popham.

Popham said Chisholm threw suspected crack cocaine out the apartment window when he was arrested.

The suspect told Channel 2's Mark Winne that he didn't have any comment other than to say he does not have a drug problem.
