A MONSTER crocodile with a penchant for horses has been harpooned and hauled from a river in the Northern Territory. The 4.5m saltwater crocodile - which would have been close to 5m long if part of its tail wasn't missing - was caught marauding about the McArthur River, near Borroloola, last night. "We believe it is the same croc reported to have attacked a horse about two weeks ago," Parks and Wildlife NT chief district ranger Eddie Webber told the Northern Territory News. The beast was caught at the junction boat ramp, more than 700km east of Darwin, about 9pm. Largest saltwater crocodile in captivity dies Mr Webber urged people in the Northern Territory to be vigilant against crocodiles. "Large saltwater crocs are known to move in and out of the area undetected at any time of the year," he said.
