'Croc that mauled teen' trapped, destined for farm or zoo

The crocodile that mauled a brash teenager foolish enough to jump into a far north Queensland river last weekend has been trapped, wildlife rangers say.

Wildlife rangers caught a four-metre crocodile in the Johnstone River in Innisfail on Friday morning, metres from where the teen was attacked.

Lee De Paauw, 18, was mauled by the reptile in the early hours of Sunday morning after he jumped into the river in an attempt to impress a British backpacker.

Authorities initially believed the crocodile was about three metres in the length, but a bite mark analysis showed the crocodile was larger than first thought.

Environment Minister Stephen Miles said the crocodile would be offered to a crocodile farm or zoo.

Mr De Paauw's stunt drew the ire of Whitsunday MP Jason Costigan, who said "we can't legislate to protect dickheads".
