Residents of Moo 1 village in Tambon Wat Toom noticed the crocodile in Klong Khuad on Monday and alerted the provincial fisheries office. The five-metre-wide canal connects Lop Buri River and Pa Sak River.
Fisheries staff rushed to the scene and erected nets across the canal to prevent the large reptile from escaping.
On Monday evening, Muang Ayutthaya district chief Witthaya Khiewrod led boats to hunt for the crocodile. A team of officials were deployed on the canalside to flush out the predator. After an hours-long search, the crocodile was finally captured at 2.10am on Tuesday.
Local fisheries officer Sompog Puengchu explained that villagers had flocked to the spot on Monday evening, prompting the croc to take cover under the water.
The crocodile weighed about 90 kilograms and did not appear fierce.
Sompong did not say whether it was a wild crocodile or a farmed beast that had escaped its pen.
It was sent to a wild animal sanctuary in Ayutthaya province.
However, while crocodiles are regularly spotted and captured in Thailand’s rural waterways, reports of people being killed and eaten by the large predators are rare.
