A teenage girl in America sparked a massive social media panic after live-Tweeting an apparent house invasion - which turned out to be a hoax.
The girl - 16-year-old Kara Alongi - tweeted on Sunday night: "There is someone in my hour ecall 911."
The message was picked up by her friends, and then by millions of connected people who urged each other to help find the girl through Twitter, Facebook and real-world searches.
Internet news site Gawker said: "There couldn't have been a bigger internet freakout if Joseph Kony himself had spirited Kara away".
By Tuesday she had more than 108,000 Twitter followers, after the hashtag #savekara trended across the US. On Facebook at least one page dedicated to finding her received 5,000 likes.
Her original Tweet was retweeted 34,899 times.
But now police say that no "foul play" was involved - and that the girl ran away voluntarily.
"We don't know why she sent (the tweet) out," said the local police chief Alan Scherb.
"Right now we are not looking at any charges."
"It sent more manpower (down) these wrong-way streets," he added. "It hampers us because we have to follow up on bogus leads."
Alongi is still missing, however, and have urged anyone with real information about where she is to get in touch with them.Suggest a correction
