Herkimer, NY (WIBX) - A suspect in custody in Ulster County is thought to be the second man wanted in the First Source Federal Credit Union robbery earlier this week.

Another man being held in Columbia County is also expected to have formal charges against him filed this afternoon.

Their names have not yet been released but Herkimer Police Investigator Jeff Crim says the men may have also robbed banks in Genesee and Monroe Counties.

He is awaiting word on when they can be brought to Herkimer for questioning.
