Indianapolis police say they have arrested a suspected serial bank robber with the help of the FBI. Agents believe 43-year-old Brinton Yates is responsible for robbing four banks in the last three weeks while he was on parole for a previous bank robbery conviction. He's accused of targeting banks on the north side. A Chase Bank on Michigan Road was hit twice. Police said Yates also held up a Chase Bank on Meridian Street and a Key Bank on Fall Creek Parkway.
