MINNEAPOLIS - An innocent bystander was caught in gunfire during a fight and subsequent shooting outside a popular downtown Minneapolis bar on Saturday night.

The shooting happened around 8 p.m. outside Lyon's Pub at 16 South 6th Street. Authorities say there was some sort of argument between two groups of younger people when several shots were fired.

The victim, a 31-year-old man who was sitting on the patio, suffered a bullet wound to a leg and was transported to Hennepin County Medical Center for treatment of a non-life threatening injury. He is listed in "satisfactory condition." According to the police report he is from the United Kingdom.

With the help of numerous witnesses, police were able to track down the group involved and detained five people for questioning at the government plaza light rail station. Investigators are also looking at video from downtown cameras and from the light rail stations. So far, no arrests have been made but a gun was recovered at the scene.

The incident brought light rail traffic to a halt on both the blue and green lines in Minneapolis for nearly an hour. By 9 p.m., trains were running again but Metro Transit said to expect significant delays as they work to get back on schedule.

Also, bullets shattered skyway windows at 7th Street and Hennepin Avenue. Crews worked to clean up the mess and board up the windows.
