A US man has been killed after being attacked by an alligator while he was swimming in a Texas bayou, news reports say.
The 28-year-old man ignored warning signs posted along the edge of the water, the reports said.
He was attacked immediately after jumping into the water, KFDM television in Beaumont, Texas reported, quoting eye-witnesses.
A female companion who had gone swimming with him tried to pull the screaming man out of the water.
She was uninjured.
Police say they found his body two hours after the attack.
