The police tried to restrain some of the crowd, knocking a few people down, which incited bystanders even more. Some of those handcuffed in the wagon escaped when police left them unattended (deliberately, according to some witnesses). As the crowd tried to overturn the police wagon, two police cars and the wagon—with a few slashed tires—left immediately, with Inspector Pine urging them to return as soon as possible. The commotion attracted more people who learned what was happening. Someone in the crowd declared that the bar had been raided because "they didn't pay off the cops", to which someone else yelled "Let's pay them off!" Coins sailed through the air towards the police as the crowd shouted "Pigs!" and "Faggot cops!" Beer cans were thrown and the police lashed out, dispersing some of the crowd who found a construction site nearby with stacks of bricks. The police, outnumbered by between 500 and 600 people, grabbed several people, including folk singer and mentor of Bob Dylan, Dave Van Ronk—who had been attracted to the revolt from a bar two doors away from the Stonewall. Though Van Ronk was not gay, he had experienced police violence when he participated in antiwar demonstrations: "As far as I was concerned, anybody who'd stand against the cops was all right with me, and that's why I stayed in... Every time you turned around the cops were pulling some outrage or another." Van Ronk was one of thirteen arrested that night. Ten police officers—including two policewomen—barricaded themselves, Van Ronk, Howard Smith (a column writer for "The Village Voice"), and several handcuffed detainees inside the Stonewall Inn for their own safety.
