A bomb threat shut down San Francisco's Union Square yesterday for approximately two hours.
The incident took place around 11:45 a.m. when an unattended backpack was discovered along Stockton Street.
In response, authorities ordered a multi-block area in the city to be closed, as workers in the vicinity were asked to remain inside their businesses and tourists were ordered to avoid the area. Cable car service was also stopped during the investigation.
Fortunately, bomb-sniffing dogs and their human colleagues did not find anything dangerous inside the suspicious device, which was sitting near a text that had been set for this weekend's women's marathon.
"It's better to be safe than sorry," Police spokesman Albie Esparza told The San Francisco Chronicle of why a shutdown was ordered. "We take these incidents really seriously."
Union Square is a major tourist draw in San Francisco. It is visited by millions every year and is comprised of many high-end retail stores.
