A trail of blood was left behind at the scene of a bank robbery and shooting on Detroit's west side Tuesday morning, Local 4 reported.

A man entered a Bank One on Joy Road near Meyers Street at about 10 a.m. and ordered a teller to give him some money, a witness told the station.

The robber fired shots after the teller reacted too slowly to his demands, the witness said. No one was hit by the gunfire.

After getting the money, the man was confronted by a retired Detroit policewoman armed with a gun. The former officer ordered the robber to halt, but the man did not listen.

The retired officer fired at the man while he attempted to flee with the bag of money, according to the station's reports.

A trail of blood indicated that the man may have been hit in the gunfire, police said. The man escaped the scene.

No other injuries were reported.

There was no word on how much money was taken from the bank.
