BALTIMORE — The Baltimore division of the FBI say the group is coordinated, detailed, and at this point unstoppable.
Two men and two women make up who the feds are calling the "Mod Squad," a group that's in their 20's or early 30's that have attempted or successfully robbed 13 banks in the Baltimore area over the last three months, including two robberies over the weekend both in Baltimore County and the city.

"They are putting some thought into this. This is not a spur of the moment decision to go out and rob these banks, each of these seem to have some level of planning," Special Agent John Krajnak said.
Krajnak is in charge of the FBI's bank robbery prevention efforts in Baltimore.
He says the group's robberies have gone in waves starting back in March, and now is pickup up again in the last few weeks.
"They consistently have a lookout that stations in the lobby or vestibule of the bank. They vary their getaway vehicles, so we're seeing different cars in these robberies, and they vary the person from the crew that approaches the victim teller," Krajnak said.
From there, Krajnak says one of the thieves threatens a bank clerk, but up to now has never revealed they have a weapon.
The feds are now relying on a task force of agents and local officers to crack down on the squad.
"The Mod Squad is up to 13 robberies and robbery attempts. For a frame of reference, there are some entire FBI divisions that have not seen 13 robberies and robbery attempts and here we have a crew that's up to 13 themselves," Krajnak said.
And it's contributing to the Baltimore area leading the country with nearly 70 bank robberies just this year and a push from agents to find this 'Mod Squad.'
A reward of up to $5,000 is being offered for information leading to the identification, arrest, and conviction of the suspects.
Anyone with information is asked to contact the FBI at 410-265-8080.
