The officers confronted the snake and snared it without incident. They say the boa constrictor is believed to have been a pet before it slithered outdoors.
The unharmed snake has been taken to a reptile store in the nearby neighborhood of Seaford.
Boa constrictors are not poisonous and are generally found in Central and South America. The snakes can grow up to 13 feet long.
They usually squeeze their prey until it suffocates.
