A man and woman on a moped were killed early Thursday when a suspected drunken driver fleeing police crashed through barricades at the South By Southwest festival in Austin and slammed into a crowd of festivalgoers, police said.

Austin Police Chief Art Acevedo said the motorist also plowed into people gathered in front of an emptying nightclub around 12:30 a.m., injuring 23 people, five critically. He eventually crashed and tried to make a getaway on foot. A police officer shocked him with a stun gun and took him into custody, Acevedo said at a news conference.
