SAN DIEGO - Cellphone video posted on YouTube appears to shows a San Diego police officer holding a person on the ground while pointing a gun at the person holding the camera.

10News watched the shaky cellphone video several times to decipher what was going on. 10News learned three men were standing outside a Rite Aid store in Carmel Valley on Sunday, and San Diego police said at around 11:20 p.m., an officer approached them and asked to see their identification. When the young men refuse, the officer starts to take one of them into custody.

In the video, a young man is heard resisting a search.

"I don't submit to any searches or seizures," he screams.

"Put that down. I've been doing this longer than you've been alive. Put that down," replied the officer.

It's not clear what the officer wants put down.

10News was tipped off to the video by an attorney who is considering representing the young men in a harassment suit.

The video shows the officer with someone face down on the ground. He then points his gun at the person holding the cellphone.

"Get over there!" the officer yells at the person with the phone.

"You do not, you cannot point the gun at me for not doing jack---. That is bull---," the young man screams back.

"Get back over there!" the officer says, apparently still pointing his gun.

"Put that gun away! You're going to shoot me for not moving back?" the cellphone holder says.

10News tried tracking down the young men in the video. Their age was not known at the time this report was written. Their age is important because if they're under 18, San Diego police said they violated the city's curfew law. SDPD spokeswoman Lt. Andrea Brown said anyone 17 years old and under needs to be home by 10 p.m.

"It was 11:20 at night and the officer was investigating curfew violations. Age is the issue. All they had to do was show their IDs," said Brown.

Brown said one of the young men is facing a misdemeanor for obstructing justice-resisting arrest. However, she couldn't say what lead to this dust up.

"The video doesn't tell the whole story. We're missing the beginning that leads up to the incident," said Brown.

In the video, you can hear one of the young men tell an officer he had a knife in his right pocket. However, nothing else is heard.
