I managed to accidently piss off someone scary just over 25 years ago. I'll call him Steve.
I'd heard about some huge Jamaican bloke about 5 years earlier who'd had some girls working as prostitutes. One of them broke free from working for him, he'd seen her a year later in a kebab shop so him and his brother had got behind the counter, took a knife and slashed her legs so he spent time in prison for that. Steve was over 7ft tall, a kick boxer with a class A drug and alcohol problem, an artist (I still own one of his works) with a high I.Q. He was also a gun dealer I later found out.
I'd bumped into a mate and was telling him about an agency who were hiring. My mate wasn't interested but 7ft+ Steve was. I still didn't realise who Steve was. He said he didn't have a bank account so like an idiot, I told him he could have his first wages paid into mine then he could open his own bank account.
Come payday and the agency screwed up so they didn't put his wages into my account. This saw me lying on the kitchen floor with my legs against a wall and my back against our flat's front door with Steve repeatedly trying to break the door open. Steve even hijacked the neighbours flat so he could get a good run up. He didn't get in and I told the ex to call the police, shouting through the door to tell him to f**k off.
After the police turned up, they were visibly shaken. One of them told me Steve must be mellowing out because in the past it had taken six officers to get him in a car. I later found out they were looking for him anyway about a post office that had been robbed in Derby.
I expected they'd bail Steve and he'd be back and he was the next evening. He was well known in the town so a mate's girlfriend advised me "We don't blame you for calling the police. If you have to again, say you think he's armed .. then they'll send an armed response unit.". That's exactly what happened. The second evening, I'd turned a sofa on it's side to barricade us in, I had sugar in the water in the kettle if he had somehow managed to get in and other set ups but he didn't get in ..
After this, I had to keep my head down. I bought a new black hooded jacket. My Dad didn't take the threat seriously so I went to Birmingham and bought a legal high-ish power air pistol then had that adapted. I had to quit the agency job because Steve was waiting for me there. Steve was attacking my mates to try to find out where I was now living. Him and his brother had already been in prison for killing someone in London. I can look after myself but I really didn't want to see what would happen with Steve and Rob.
