Authorities say shark attacks 4 beachgoers in Texas on July 4

On July 4, a shark reportedly attacked four people off the south coast of Texas.

According to a July 4 press release from the Texas Parks and Wildlife Department, authorities received reports that four people were attacked by a shark on South Padre Island.

“Current details indicate that two people were bitten and two people came into contact with the shark but were not seriously injured,” the press release said.

According to ABC News, South Padre Island police said they received a call around 11 a.m. local time reporting a man suffering from a “severe” shark bite to the leg.

A post shared on Facebook said that “two off-duty Border Patrol agents from the Laredo Sector responded to a shark attack on South Padre Island today.” The post, which showed two photos of a person being treated on the beach, added that the agents “pulled the shark attack victim from the water and rendered life-saving aid.”

The two bite victims were taken to Valley Regional Medical Center in the city of Brownsville, according to the press release from the Texas Parks and Wildlife Department. One of the victims was flown out for “further treatment.”

The condition of the two bite victims is unknown, according to local media outlet KRGV.

Captain Chris Dowdy, game warden, told the outlet that the third person was injured while trying to fend off the shark and required stitches, while another person suffered grazed wounds and minor injuries.

Dowdy added that the shark escaped into open water.

Following the attacks, the Texas Department of Public Safety patrolled the area with helicopters, while game wardens and members of the Texas Game Warden Marine Tactical Operations Group helped patrol the beach with boats.

“Encounters with sharks of this type are not common occurrences in Texas,” the Texas Parks and Wildlife Department said in its press release. “When shark bites do occur, they are usually a case of mistaken identity by sharks searching for food.”

“If you see large schools of bait near shore, it is usually an indication that a predator is nearby. If you see a shark in the water, calmly exit the water and wait for the predator to pass,” the press release continues.

South Padre Island police and fire departments did not immediately respond to PEOPLE’s request for further information.
