At least two people were arrested at gunpoint after a flash mob of shoplifters robbed a California department store late Saturday night, a report said.

The incident happened at the Walnut Creek Nordstrom store, according to NBC Bay Area reporter Jodi Hernandez.

Some two dozen cars blocked the street as throngs of robbers rushed the store, made off with merchandise and sped away, the reporter tweeted.

Cops with guns drawn arrested two suspects, she said.
