Update 4:15 p.m. The person behind the @HiddenCash Twitter phenomenon promised more cash drops in Los Angeles on Friday.
About to do more drops in LA. Give me a couple hours. Traffic and logistics... Clues coming.— Hidden Cash (@HiddenCash) May 30, 2014
Update 10:33 a.m.
The first cash drop on Friday was found near Old Firehouse Recording Studio in Pasadena around 10:20 a.m. The winner, Cassandra Mercury, is a Pasadena resident.
Previously 10:13 a.m. The scavenger hunt for hidden cash continued in Los Angeles area on Friday after its second round of money drops sparked a frenzy in Burbank.
According to the latest Tweet from @HiddenCash, there will be 3 more drops in L.A. Friday morning and a few more coming in the evening. Two clues for the first drop have already been released.
On Thursday night, hundreds of people were drawn to the Burbank Empire Center, seeking the hidden envelopes stuffed with cash based on hints from the Twitter account.
A few lucky ones succeeded in the treasure hunt, including 14-year-old Tatiana Ramirez, who told CBS the money will go to her grandmother’s medical bills. People were asked to post their photos with the money they found and tag @HiddenCash on Twitter.
The crowd was so large and fervent that police arrived in the area to make sure nothing got out of control, NBC reports.
In a statement released on Friday morning, the so-called "Mr. Hidden Cash" warned people to "walk and drive safely" and " be respectful to the locations themselves and surrounding businesses."
The mysterious operator behind the account made his first appearance online on May 23rd and started his first “social experiment for good” in San Francisco, dropping money all over the Bay Area and tweeting out clues about the locations.
The movement arrived in Los Angeles on Wednesday, and the anonymous millionaire plans to remain in L.A. through the weekend, according to CBS2.
On Twitter, @HiddenCash said he'll keep the movement going but be more careful about location selection to make sure it’s safe.
“We want to encourage people to be kind, to be generous, and to pay it forward," he said.
The Twitter account @HiddenCash has attracted more than 300,000 followers as of Thursday evening — a week after the account was created.
