An irate gamer, frustrated at losing a Call Of Duty match against a rival player, made a hoax phone call that resulted in a SWAT team arriving at his house.
More than 60 armed officers approached the home of 17-year-old Rafael Castillo of Long Island, New York, after the call was made.
The caller, who has yet to be identified, had been playing online against Castillo at Call Of Duty, and became frustrated when a particularly intense game resulted in his defeat.
To get his own back on Castillo, the player found out his name and location and called the Long Island police, informing them that he was Castillo and had shot his mother and brother dead, and was planning to kill more people.
Police scrambled a large squad of officers, helicopters and special ops members to Castillo's house, where after a tense two-hour stand-off it was revealed that Castillo's mother and brother were alive and well.
An oblivious Castillo, who was still playing in his bedroom with headphones on, was unaware of the drama going on outside his house until his brother entered his room and told him the police were looking for him.
"I right away had an idea what it was, because I've seen [similar pranks] on the news," Castillo told the New York Post.
"It was probably just an evil little kid," added a police officer at the scene.
"We went and checked out the place and there was nothing there.
"It sucked up a lot of resources, caused traffic problems. It turned out to be a hoax."
