Police overtime pay comprised the majority of overtime expenses at $97,200. Ten protesters were arrested for obstructing on the evening of October 13 after refusing to vacate Westlake Park after it had closed. On October 15, the Occupy Seattle movement had its largest demonstration to date, with over 3,000 people rallying in Westlake Park. On the morning of October 17, 2011, Seattle police informed campers at Westlake Park that tents had to be removed for city personnel to clean the park. It was reported that during this incident six demonstrators who didn't comply with the order were arrested. The city of Seattle issued permits for Occupy Seattle on October 18, 2011, which limits camping at Westlake Park and enforces the park's closure at 10:00 PM. Another permit for protests occurring at Seattle's city hall plaza allows camping with the stipulation that tents are to be deconstructed by 7:00 AM. It was reported that police are enforcing a rule in Westlake Park in which umbrellas are only allowed to be used while being held, and are not allowed to be used as tent-like shelters. On November 2, Occupy Seattle protesters demonstrated at a Chase Bank on 12th Ave; the demonstration was a reaction to Chase CEO Jamie Dimon's visit to Seattle. At 3:00, five protesters entered the bank and linked together via chain and pieces of PVC and facing out from the tellers. In addition about a dozen demonstrators sat in front of the police van to prevent it from moving and were eventually pulled away. After being warned to leave the bank, Seattle Police arrested the demonstrators. During the demonstration, ten police officers were physically assaulted by protesters, one officer was struck with an empty beer bottle, two suffered minor injuries. Pepper spray was used to provide cover for the officers under attack and disperse the assailants. On November 15, a march commenced from the Seattle Central Community College campus to Belltown. At one point during the march, a 17-year-old female swung a stick at an officer. After officers moved in to arrest the female, the officers were hindered in their efforts; after issuing an order to disperse the officers deployed pepper spray to move subjects away from them so they could arrest the female suspect. Police were filmed spraying the crowd of people with pepper spray. It was reported that the victims included "a 4-foot 10-inch, 84-year-old woman, a priest and a woman, Jennifer Fox, who claimed the pepper spray led to a miscarriage." However, doubts have been cast on the truth of Fox's claim of pregnancy.
