A 28-year-old smashed the window of a police car after rowing with her partner in Bideford, a court has heard.
Lucie Brydges, 28, from Monkleigh, pleaded guilty to assaulting a constable and causing criminal damage on August 17 this year.
Magistrates heard Brydges was in Bideford town centre at around 6.30pm with her boyfriend. They had both been drinking heavily.
There had been an incident between the pair and police were called to the scene.
Brydges became very aggressive with police and attempted to pull away from the arresting officer.
She was eventually handcuffed and placed in the police car where she began to kick out and smashed the rear near-side window of the car.
PC Simon Willan opened the car door and attempted to calm her down, but Brydges lashed out and grabbed his left cheek.
She was restrained and taken into custody.
Sara Svensson, for the defence, said Brydges could not remember kicking out in the car, but after watching CCTV footage admitted she obviously had done.
Miss Svensson added: “Miss Brydges was very upset and wound up that she was being targeted as a defendant not a victim.
“She was trying to say ‘you have got the wrong person’.”
Magistrates fined Brydges £265 along with a victim surcharged of £26, costs of £85 and compensation of £150.
She also pleaded not guilty to using threatening words or behaviour in a separate incident outside her house on September 11.
This case will be dealt with at a trial on December 2.
