The giant male carnivorous species was sighted in the rivulet near Bilabalrampur village last week which had triggered panic in the riverside areas with the people becoming apprehensive of a possible attack.
"It had strayed from Satakosia gorge of Mahanadi river system and might have adapted itself to the new water body in its search of a suitable habitat," DFO Bimal Prasanna Acharya said.
While 1671 estuarine crocodiles are in Bhitarkanika area, the mugger population stands at 116, he said.
The mugger species after being captured was handed over to Nandankanan zoological park officials as it could be better protected and taken care of by the park authorities, officials said.

"We had a tough time in capturing it. We had deployed a service group of skilled fishermen from Bhitarkanika national park to catch the animal alive," forest range officer, Himanshu Kumar Muduli, said.
First, they located it and then chased it to a narrow creek with bamboo sticks and nets.
After that, they hurled fishing nets to net it. The crocodile failed to retreat and got entangled in the nets.
"Best possible efforts had been made so that no harm was done to the animal during the operation," the range officer said.
Of late the straying of crocodiles into thickly - populated localities have become a matter of concern for the forest authorities.
