Authorities believe a single shark attacked four swimmers on Thursday at South Padre Island, Texas, leaving one victim with a serious injury to her lower leg. You can see photos of the incident here, but be advised that they’re graphic in nature. 

Texas Parks and Wildlife officials said it appeared the shark was involved in four separate incidents which resulted in two bites, one severe and another injured, fending off the shark. 

The Independence Day attacks followed reports of several large sharks along the eastern and southeastern coast earlier this week, including a massive 13-foot great white detected off the coast of Florida on Wednesday.
