Horror video shows moments after shark attack off US coast that left swimmer with major injuries to stomach and leg

The shark attack occurred only 150 yards out in the water.

Paul Bandy, a police officer, and his wife, Aimee Johns who's a nurse, were paddle boarding nearby when they went to help Bruemmer.

Bandy told KSBW 8: “He was screaming for help, you could tell the sound and the emotion in his voice that there was something definitely wrong and he was slapping the water.

“I wasn’t sure if that was some sort of thing he was trying to get something away from him or just trying to draw attention to himself."

Heath Braddock, a local surfer, assisted the Bandy and Johns.

"We got my biggest board and the gentleman, Paul, helped me roll the victim on the board belly down and got him kind of centered and stable," he said.

"We had him hold my foot and we paddled him in."

"We had to quickly cut his wet suit off of him and open it all up and try to apply the tourniquets to each limb and also to his abdomen," Johns added

"Put the pressure there because he was bleeding severely."

Bruemmer sustained significant injuries from a confirmed shark bite, the Pacific Grove Police Department told The Sun.

The victim was immediately taken to Natividad Medical Center, a trauma center 23 miles from the beach.
