Emergency responders swarmed a Long Island home Tuesday, reacting to what they believed was a hostage situation and possible murder scene, only to find out that the call was a hoax to take revenge against a video game rival, authorities said.

About 70 police officers landed at a home on Laurelton Boulevard in Long Beach after receiving a 911 call from someone claiming to have killed his mother and brother there, NBC News reported.

However, it was discovered that the call was a hoax and no one from the home had made a call to 911. Instead, a 17-year-old boy believed to be the target of a hoax was playing "Call of Duty", and his family was fine.

The hoax appears to be a popular trend among online video game players called a "swatting" prank.

"When a bunch of people play, the loser will gather information on the winner and will call police in that jurisdiction, say 'I'm so and so, I shot my mother, brother' and try to get his response, and today, it did happen," said Long Beach Police Commissioner Michael Tangney.

"In this ... bizarre world of Swatting, you get points for the helicopter, for the police cars, for the SWAT team, for the type of entry," Michael Tagney told the local station. "It's very sophisticated. Unfortunately, it's very dangerous."

Taking the call "very seriously," the police surrounded the home and brought the three people out of the house to ensure their safety, NBC News reported.

When authorities determined the call was a hoax, Tangney said he was "very angry."

"It's a tremendous waste of taxpayer resources, tremendous danger to law enforcement," he said.

The caller "did something so, so foolish and so dangerous," Tangney added.

The person who made the 911 call "could be anywhere in the world," according to Tangney.

With the teen's game console being taken in for evidence, investigators will try to figure out the identity of the call and where the call was made from.
