A fight between two groups turned deadly in Florida when a shooting in a Tampa street during Halloween festivities resulted in two deaths and 18 people hospitalized early Sunday morning, police said. One suspect is in custody and at least one more is being sought.

Video posted online shows people, many in Halloween costumes, drinking and talking on the street when about a dozen shots ring out followed seconds later by about eight more, creating a stampede. Some people topple over metal tables and take cover behind them. Video from the aftermath shows police officers treating several people lying wounded on the ground.
