Bonomo then said she was an artist. “You’re an artist? Have you got any proof or any identification?” he said. After accusing Bonomo of being cocky, the PCSO said she had been cycling the wrong way down a one-way street and threatened to fine her. After she apologised, the PCSOs departed, but returned moments later with about six police officers, she said. She was searched and, after an altercation with one officer, was accused of being aggressive, bundled to the ground and arrested.
The PCSOs were not involved in the arrest. After five hours in a police cell, Bonomo said she was told to sign an £80 fixed penalty fine for a public order offence. She plans to contest the penalty, which stipulated she caused “harassment, alarm and distress” in public. Bonomo returned the next day to interview builders who had witnessed her arrest. Footage of the interviews appears to corroborate her account. “I was disgusted,” one said. “They were terribly out of order. There was one officer who was spiteful to you.” The Met confirmed that a woman was stopped and searched under section 44 of the Terrorism Act. Any complaint made to police would be fully investigated.
