DOWNEY, Calif. (KABC) -- A crowded Walmart in Downey was evacuated after a sudden sound set off a panic inside the store.
The Downey Police Department quickly responded to the store in the 9001 block of Apollo Way around 9 p.m. Friday and tried to determine what the sound was that made customers run for the exits.
People inside took to Twitter reporting everything from a loud popping noise to a man running in the store with a knife.
AIR7 HD was overhead as dozens of people stood idly by a nearby Chase bank.
Police said a group of teens who were inside the store were trying to pull off a prank and film it for YouTube. Police believe something those teens did sparked the panic.
