MINNEAPOLIS (AP) - Authorities in Minneapolis say they've made arrests and restored order after a large, chaotic group of young people blocked traffic and got into fights amid St. Patrick's Day celebrations in downtown.

Minnesota Police Department spokesman John Elder says it appears the group came into town with the intention of causing trouble.

Elder said at a news conference late Tuesday that police are still gathering information. He didn't have an exact number of arrests.

There were no major disruptions to light rail but buses were rerouted temporarily. Elder says they were used to evacuate people from the most "troublesome" areas.

Police also reported a shooting in a separate area of downtown Tuesday that injured one person. No one is in custody. It wasn't immediately clear whether the shooting was related to the disturbance.
