A Los Angeles County sheriff's deputy is under the investigation after a video posted online which showed him ignoring a shooting call while he recorded a message to his then-girlfriend, the officials said on Thursday.

The video posted on YouTube in the last month shows Deputy Jeremy Fennell in a patrol car talking into the camera as a dispatcher is heard relaying the shooting alert.

The deputy used colorful language and then looked into the camera and said, "Someone got shot. Oh well."

As the 51-second video clip comes to end, Fennell blow kisses and said he will see the woman later that evening.

Priscilla Anderson, Fennell's ex-girlfriend, said that she posted the video online because she wanted to bring attention to the Fennell’s behavior after being ignored when she contacted his supervisors. She also said the video was recorded in December.

"I was shocked and saying, 'Oh my god. There's no way you could do something like this,'" Anderson said on Thursday as she recalled receiving the video.

She said that she also sent the supervisors other videos of Fennell being rude to the people on street.

Anderson said that Fennell sent her videos he recorded in his patrol car with the fellow deputies to get her to call him back.

An investigation was immediately launched after the agency learned of the shooting alert video, said Lt. Darren Harris, the sheriff's spokesman.

A call to a number listed for Fennell in the public records went unanswered. The union which represents deputies said it looks forward to a full and impartial investigation.

Anderson said Fennell grew angry one night in the January when she tried to end their relationship, grabbed her by the neck and he also pulled out his gun.

Later, Fennell was arrested in two days on suspicion of domestic violence and also was placed on desk duty. The sheriff's department investigation into that incident is also underway, said Harris.

Shiara Davila-Morales, a spokeswoman for the Los Angeles County district attorney's office said that the case is under review.
