joining us. I'm Terry McSweeney and I'm Gia Vang, a busy night for police in several Bay Area cities. At this hour. Officers in Oakland responding to several sideshows across the city. In San Jose, several street closures remain in place and police are investigating a stabbing that left a child and adult injured. It happened near where Cinco de Mayo celebrations were taking place.

He was taken to the hospital where right now he is fighting for his life in critical condition. And this all happened near Emma Farm Park, off King Road. The stabbing happened shortly before 530 tonight near where Cinco de Mayo celebrations were taking place off King Road. It's unclear if the violence is connected to those celebrations. To celebrate, Yesenia Angeles says she believes Cinco de Mayo celebrations may have increased the risk of violence as police searched for a suspect on foot. A police helicopter circled the area using a loudspeaker to warn drivers to leave the plaza at King and Story, or risk having their vehicles towed near downtown. Police closed the Park Avenue off ramp off southbound highway 85. Police say they also focused on crowd control on Santa Clara Street because of safety concerns, including fights, reckless driving and sideshow activity.

Cinco de Mayo it just brings a lot of the Mexican culture out to their community, and so definitely enjoying the fact that we can all be together and everybody else. Diversity everything else I've seen throughout the streets. So it's been fun to enjoy that. Police diverting cars onto fourth Street as a parade of
