EMERGENCY services were scouring a river in the Northern Territory over the weekend after a crocodile attacked a swimmer.
Police received a report at 4pm on Saturday a crocodile had attacked a 24 year old man while he was swimming in the Mary River.
Northern Territory Police watch commander Senior Sergeant Peter Lindfield said water police and response group officers were at the scene searching for the crocodile and the missing swimmer.
It's understood the man and his friends were staying at a nearby caravan park when they decided to go for a swim.
Mary River Wilderness Retreat and Caravan Park employee Erin Bayard told News Limited she always told people to stay away from the river.
"Its one of the most populated rivers in the territory, every couple of kilometres there is a large croc," she said.
According to the ABC, a friend saw the crocodile take the man and swim up the river with the victim in its jaws.
Multiple crocodiles were shot during the search for the man's remains.
The attack occurred about 110km from Darwin.
