A man walking through New Orleans floodwaters caused by Hurricane Ida was attacked by a large alligator and is now missing, a Louisiana sheriff has said.
The 71-year-old man's wife told sheriff's deputies that she heard a commotion at around noon on Monday, then walked outside to see the gator attacking her husband in the New Orleans suburb of Slidell, the St Tammany Parish Sheriff's Office said in a statement.
"Once the attack stopped, she pulled her husband out of the floodwaters, and returned inside to gather first aid supplies," the sheriff's office said.
When the man's wife realised how severely her husband had been injured, she got into her canoe and went to higher ground - about a mile away - to get help.
But when she returned, her husband was no longer lying on the steps of their home, the sheriff's office said.
The sheriff's office said it used high-water vehicles and boats in an attempt to find the man "but all attempts have been futile".
The man was not identified by the sheriff's office and few other details were immediately available.
The sheriff's office is warning residents to be on guard while walking in flooded areas as wildlife have been displaced during Ida and might have moved closer to neighbourhoods.
