(CNN) -- A surfer died Tuesday after a shark bit him off the coast of a Southern California air force base, authorities said. Francisco Javier Solorio Jr., 39, was riding waves Tuesday morning with three friends when he was bitten, according to Santa Barbara Sheriff's Office. One of the friends saw the attack, swam over and pulled Solorio out of the water and onto the beach, Sgt. Mark Williams with the sheriff's office said. The friend gave him first aid while another called for help, he said. Paramedics pronounced Solorio dead at the scene, the sheriff's office said. The four friends were surfing at Surf Beach, located on the Vandenberg Air Force Base, whose fire department responded to the emergency call, authorities said.
