The bird eluded officers in St. John for about two hours Friday before police managed to throw a net over it, The Times of Munster reported.
The bird was turned over to animal control officers. Police Chief Fred Frego said he believed it was the first time local police had captured an ostrich.
Frego said he had "no clue" where the bird came from.
"We don't have any missing ostrich reports," he said.
