Minutes after a woman opened fire on YouTube's San Bruno, California campus, employees returned to the building they'd just fled to help police officers access the office.。

In a new statement Wednesday, the company praised employees and first responders for their "acts of heroism" following the shooting.  。

"Yesterday's horrific act of violence was deeply shocking and disturbing to our YouTube Family. Still, we are uplifted by the heroic acts we witnessed from both employees and the San Bruno community, especially the first responders," the company wrote.。

The company described the San Bruno Police Department's response as "exceptional." The SBPD said Tuesday it arrived on the scene within two minutes of receiving the first 911 calls.。

The company also called out employees who went back into the building after police arrived in order to help them enter YouTube's offices. (YouTube, like many other tech companies requires employees to use a keycard to access much of the premises.)。

Meanwhile, other employees stayed behind with the people who had been injured and to give police officers a description of the suspected shooter.。

YouTube also confirmed that the shooter was never able to access the inside of any of the company's buildings. Instead, she entered an outdoor courtyard via a parking garage. The company said they will be "revisiting this incident in detail and will be increasing the security we have at all of our offices worldwide to make them more secure." 。
