WATCH: Crooks spend hours looting brewery while bystanders do nothing

TACOMA, WA -- Surveillance cameras captured a string of different thieves looting a bike themed brewery in Washington state. More disturbing: the fact no witnesses called 911 to report the crimes.

The first thief threw a piece of concrete through the window of Sluggo Brewing Monday morning, ABC affiliate KOMO-TV reports. He walked off with a mountain bike.

Several other people then came through the broken window and left with skateboards or bikes. The thefts went on for four hours.

One brewery employee says he's not just mad at the thieves, he's also mad at bystanders who can be seen in surveillance video doing nothing.

"When people are just casually walking by and see it then that's kind of odd to me that no one called 911," says Joe Abarca.

The thefts were a blow for the brewery which was preparing for its grand opening. Friends of the businesses started a GoFundMe page to help them replace what was stolen.
