What is being called a case of road rage led to a shooting Friday outside a credit union on East Ireland Road in South Bend.

It happened just before noon.

Police say the shooting happened outside the Teachers Credit Union branch near Ironwood.

South Bend police say a 21-year-old man was shot in the shoulder late Friday morning. He suffered injuries that are not considered life-threatening.

The man who fired the gun, 31-year-old Maurice Conley, has been arrested for battery with a deadly weapon and criminal recklessness, South Bend police spokesman Ken Garcia said in a release issued Friday night.

Investigators say the incident began with "driving behaviors" near Lincoln Way and Ironwood. Conley reportedly followed the other man's vehicle to the credit union parking lot.

Police say the two cars ended up in the TCU drive-thru with a man and a woman in each vehicle.

"A physical confrontation then began between a female in Conley's vehicle and a pregnant female from the victim's vehicle," Friday night's release says. "The victim was shot after attempts to end the fight."

The woman who was attacked, the man who was shot and the pregnant woman who was with him all were transported to the hospital.

Investigators say the credit union was not connected to the incident, though the branch did close for a few hours before reopening at 3 p.m.

The other three people other than Conley who were involved in the incident have not yet been publicly identified.

NOTE: Police initially said the shooting was the result of someone attacking Conley's companion. In Friday night's release, department officials clarified that those reports later proved inaccurate.
