A crocodile that wandered several kilometres into the outback town of Fitzroy Crossing has been apprehended by surprised police.

The two-metre-long reptile was reported to be in the town's industrial area, in Western Australia's far north, yesterday.

Senior Sergeant Danial Strachan said it was one of the stranger call-outs he had received.

"When they snap, even though it's a freshie, it's quite terrifying," he said.

Freshwater crocodiles are abundant in the nearby Fitzroy River but it is highly unusual to see one so far from the riverbank.

The discovery comes after researchers predicted crocodile movements would be on the rise in the region after a record wet season.

"It's amazing, it would have had to walk at least two or three kilometres," Sgt Strachan said.

Already concerned for his officers' safety, Sgt Strachan said he was also worried about the reptile's health.

"It's been there all night so it looked pretty worse for wear. We raced out there to try and save it," he said.

After assessing the situation, the officers were able to capture the animal safely and return it to its habitat in the back of a squad car.

"We've managed to grab it, put it in the back of the police car, then drive it five kilometres back to the river," he said.

Despite the short stint in custody, officers said the croc appeared appreciative once it was back in the river.

"It even lifted up its head in the water — I guess as a gesture of thanks," Sgt Strachan said.

It's never a dull day in Fitzroy Crossing.

It is the latest example of the Fitzroy Crossing Police going above and beyond for the town, and its reptilian visitors.

The station is currently a finalist in this year's WA Police Excellency Awards.
