It happened around 6:30am Tuesday at a Chase bank on FM 1960 and Torrey Chase in northwest Harris County.
The FBI has talked about takeover-style bank robberies before, but this goes far beyond that.
Before the bank opened for business, there was an intruder who got in the building and overtook the two female tellers at gunpoint. Then he's said to have fired the gun.
"Several gunshots were fired from his handgun at the wall of the bank," said Shauna Dunlap with the Houston FBI.
It escalated from verbal threats to physical violence. The robber, said to be a man who concealed his face and head, lashed out at the two women.
"They were at least physically assaulted. One was at least assaulted with the weapon, so she was struck with the weapon," Dunlap said.
Some 30 minutes later, the sheriff's department received a call from the bank. Both tellers were taken to a hospital to be checked out. Their injuries are not believed to be life-threatening, but they could have been. This, the FBI says, was not a typical bank robbery.
"That is a more aggressive tactic than we typically see," Dunlap said.
Security video outside the bank shows at least two suspicious car in the area at the time. The FBI is examining it, along with video from inside the bank. So far, neither video has been made available to the public.
