A bystander trying to break up a fight was shot in the groin during a shootout on Lower Greenville late Wednesday, police said.

Officers were dispatched to the 2100 block of Greenville Avenue, near the Trader Joe's at Prospect, just after 10:50 p.m.

During the investigation, police found that the bystander walked away after initially trying to intervene because one of the men fighting pulled out a handgun, Dallas police spokeswoman Melinda Gutierrez said.

The other man in the argument also pulled out a handgun and approached the other gunman, Gutierrez said. They both started shooting at each other.

Amid the exchange of gunfire, the bystander was shot. He was taken to a hospital with non-life-threatening injuries.

The shooters fled before officers arrived. A detailed description of the men was not available.

The investigation is ongoing, Gutierrez said.
