A nasty crash in San Francisco resulted in three arrests and one gun being taken off the streets.

San Francisco police tell KRON4 this is a criminal investigation. That still has many unanswered questions on Wednesday night.

One man on the ground with his hands behind his back talked with San Francisco police about this nasty car crash by the Broadway tunnel.

Now, three people are under arrest.

“It did look like a person was trying to flee, but we did take custody of that person,” Officer Grace Gatpandan said.

San Francisco police tell KRON4 three cars were involved in the accident. And three people went to the hospital hurt after the wreck. 

It is unclear how many people were in each car. Airbags were deployed in a black Porsche.

Many people also called 911 and talked with officers at the scene about what they saw.

Only KRON4 has video of the gun recovered underneath a parked car.

The weapon is now evidence.

“There was a gun found at the scene, but it is unclear exactly what role that plans into the situation,” Gatpandan said. “We do have a traffic collision, but it is very likely that this involves a criminal investigation.”

Police are still trying to determine which car is responsible for the crash and why.

Plus, police are determining if any of the cars were stolen or if drugs or alcohol were involved.
