Seven people have been arrested this morning in connection with Occupy demonstrations that are blocking two banks in San Francisco’s Financial District as part of a daylong protest in The City, a police spokesman said.

The protesters, who had chained themselves to the Sacramento Street side of Wells Fargo’s corporate headquarters at 420 Montgomery St., were arrested on suspicion of creating a public safety hazard, police spokesman Sgt. Daryl Fong said.

Protesters had blocked entrances on all four sides of the Wells Fargo building earlier this morning and a large yellow banner was put up on a window of the building saying “We are unstoppable.”

Then shortly before 9 a.m., protesters began blocking a nearby Bank of America branch at 345 Montgomery St.

A 45-year-old Berkeley man named Cheche, who did not want to give his last name, said he showed up outside the Wells Fargo building at about 6 a.m. today.

“We didn’t know what to expect from the cops, and they stayed neutral,” he said.

However, police in riot gear began to move in on the protesters shortly after 9 a.m. and made the arrests on the Sacramento Street side of the building.

The other three sides of the building remained blocked by protesters as of 9:45 a.m.

Protesters also remained in front of the Bank of America building, and Montgomery Street was blocked off between Pine and California streets as of 10 a.m.

The protests are part of a day of action planned by Occupy San Francisco and other groups that are calling on banks to end what they say are predatory eviction and foreclosure practices.

Other actions planned in San Francisco today include an “Occupy the Courts” event planned for noon at the 9th U.S. Circuit Court of Appeals at 95 Seventh St. and a 5 p.m. march from Justin Herman Plaza, according to organizers.
