The Texas Parks & Wildlife Department said later in a statement that two people were bitten and two more “encountered” the shark but were not seriously hurt. One of the bite victims was taken to a hospital in Brownsville, and the other was “flown out for further treatment.”
Based on witness reports and images on social media, Game Warden Capt. Chris Dowdy said, authorities believe a single shark about 6 feet (about 1.8 meters) long was responsible.
Beach patrol, firefighters and police were patrolling the shore and flying drones after the attacks, Soto said.
The last reported shark attack in the area was five years ago, according to Dowdy.
Texas Parks & Wildlife is assisting the investigation.
