Police were called to the ITN production studios in central London on Aug. 23, according to the Met Police, after a group "unlawfully gained access to the building."

Two hours later the protesters had left, according to police.

Estimates suggest there were about 100 people in the group.

They appear to be part of a larger group of protesters in the area.

Less than a mile away, other protesters were gathering for about an hour outside the Google building in central London, where police prevented them from entering.

At around 2 p.m. the Met Police said in a statement: "Officers are responding to a demonstration at a private premises on Gray's Inn Road, where people have unlawfully gained access to the building. Officers are on scene engaging with building security and removing those who have gained entry."

An hour-and-a-half later, the police said that the protesters had left the building.
