The world of big tech conferences is usually a tightly controlled one, but two protesters managed to briefly—very briefly—get a moment of attention at Google's I/O conference before being dragged away by security.

The brief disruptions took place less than a day after a group of protesters calling themselves "Occupy Google" gathered at the company's Mountain View headquarters to talk about net neutrality—a cause Google has voiced some support for, most recently opposing the FCC's proposed Internet fast lanes. About 10 members of the Occupy Google group were arrested last night.

It isn't clear if there's a connection between the two individuals from today's I/O keynote and the Occupy Google group. Each protester at I/O cited different reasons for wanting to confront the search giant.

The first protester told the assembled Google crowd to "develop a conscience." She held up a sign reading "Stop Jack Halprin," referring to a Google lawyer who was protested in April when he evicted several San Francisco residents from an apartment building he owns.

She repeated the "develop a conscience" line several times, until security escorted her out after about 30 seconds. According to TechCrunch, the first protester was Claudia Tirado, an elementary school teacher who was one of the residents evicted by Halprin.

The second protester stood up about halfway through the keynote speech yelling: "You work for a totalitarian company that builds robots that kill people!" He repeated this line over and over again and was able to briefly stop the activity on stage. He was also escorted out within less than a minute. (His rallying cry appears to be a reference to Google's late 2013 acquisition of Boston Dynamics.)

A few members of the generally pro-Google audience yelled "Go home!" to the protesters when they started making noise. In both cases, the Google execs onstage didn't really acknowledge the incidents, although Engineering Director Dave Burke made what was presumably a light joke about the protest once the protesters had been kicked out.

"The battery saver is great, when you're going to embark on a long trip or a long protest!" quipped Burke.

The inside protesters had a few allies outside who picketed over gentrification and eviction issues. TechCrunch has pictures of the protesters, including one who wore a Yoda mask.

Tuesday's separate protest at Mountain View, in which demonstrators wore blue shirts reading "Defend Internet Freedom," was allowed to continue throughout the day. However, Google called the police when the group made clear it intended to stay overnight.

Mountain View police Sgt. Saul Jaeger told the San Jose Mercury News that the protesters were warned several times they would have to leave before they were arrested. Google told the protesters that they could return in the morning if they wished, Jaeger noted.

Occupy Google's Twitter feed has images from throughout the day—including police interactions and some of the protestors forming a human "Google." The feed also disputes some of what's in the Mercury News report, most notably stating that police told protestors to not return on Wednesday. The group's final message, post-arrests, promises there will be no radio silence. "#OccupyGoogle lives. After 10 arrests, we will come back 10 times as strong. Expect us."

According to spokesman Albie Esparza, the San Francisco Police Department did not arrest anyone at the protest.

"By the time police got there the protesters had dispersed and the protest was peaceful," he told Ars.
