(CNN) -- Eight people were shot Monday night just blocks from the Chesapeake Energy Arena as large crowds were leaving the playoff game between the Los Angeles Lakers and the Oklahoma City Thunder, police said. Authorities were trying to determine what led to the shootings that occurred at about 11:35 p.m., said Capt. Dexter Nelson of the Oklahoma City Police Department. Of the victims, one was in critical condition and seven suffered non-life-threatening injuries, Nelson said. Also, a woman was injured when she was punched and kicked in the crowded streets, authorities said. Thousands of people were in the area because the Thunder beat the Lakers 106-90 to advance to the Western Conference finals. "Whenever you get about 8,000 people outside of a venue, we are going to be outnumbered," Nelson told CNN affiliate KOCO. "You can't have enough people down here for that." Several people had been questioned about the shootings, but no arrests had been made Monday night, Nelson said.
