Had a row with the other half at a hotel in scotland. I left the hotel during the altercation and didn’t want to go back so I sat in the car. It was early morning around 4.30am. He then came and sat in the car too. I was in the drivers seat but he had the keys. Minutes later the police rocked up. Cuffed me at the car, breathalized me and took me away for ‘drink driving’ I was then however, released 14 hours later with a court date for ‘drunk in charge’ I’m confused as to why they arrested me for drunk driving but charged and released me with drunk in charge??
