I won't go in to massive detail as I have just given a statement to the police but I've been involved in a very unsettling incident. Cut a long story short...was walking to a tube station on my way to work one morning when an unsavory character cycled towards me from the opposite direction in the middle of a narrow pavement at some pace making no attempt to avoid me. I braced a hand close to my body to avoid his handle bar hitting me or getting caught in my jacket. A few seconds later he's perhaps 7 meters behind me shouting aggressive abuse at me. I shout back suggesting he just 'walk' away as I attempt to do the same by turning back the way I was heading expecting him to get a last insult out and do one....but no. I now have a highly aggressive, shady character complete with his hood up and fuzz over his top lip spitting with rage shouting "effing fight me", I again attempt to go our separate ways but now he's walking towards me, shaping up for a physical tear up saying "nah, nah, nah, we're gonna fight" This is all happening at a red traffic lights with many people watching on from their cars by the way. Anyway, it is abundantly clear that first thing in the morning, me, middle class, friendly guy in my mid thirties either has to try and outrun a bike or reluctantly engage. I really don't want to get in some fist fight with anyone, let alone some hooded thug with half a brain cell but have a few seconds to make my move so as soon as he got within striking distance I get him in a headlock and take him to the ground, push myself up and am standing over him on the pavement with my foot on his midriff to pin him there. Even at this point I'm still telling him to walk away in the most civilized way the situation allows while he's still a giving me the most vulgar threats etc. With him on the ground I make my exit and briskly head towards the station. I keep checking behind me every few seconds and a short while later see him circling around on his bike about 30 meters behind. Then, menacingly the only time during the confrontation he's completely silent and about a minute after I've left the initial location I turn to check again and he's cycling up behind me about 7 meters away with a modern house brick in his hand. Not surprisingly I freak out, run in to the road where there is still traffic sitting and jump in to the back of a complete strangers car and shout at him what's happening. The guy circles again looking for which car I got in and when he finds me much to my dismay he manages to open the door on the other side of the car. I manage to pull it back and lock it but the window is also part down and he's stalking the stationary vehicle making all sorts of nasty threats, that he'll remember my face etc, he also looked like he was trying to call some people and I think he's potentially a gang member or at least is among a nasty crowd. I took the opportunity from the safety of the car to take some pictures of him on my phone and got some decent shots, the downside was it gave him the same idea. I tried to cover up but he'll have some partial close ups of me and maybe a clear one, I just don't know. Finally I got away. However I am quite shaken up by this. It was a few hundred meters from my house bang in the middle of my home and route to work, even this idiot might work out I was heading to the tube and on my way to work as part of my routine. He's a guy prepared to hit a guy on the back of the head with a brick and probably has my picture, he'll clearly remember me if our paths cross. He likely loiters locally on a bike so if he does spot me I'm in trouble. The police now have my statement and a good picture of him so I'm hoping he'll be known to someone, if he knows he's been identified I'll feel a whole lot safer. I have faith in the police to do their thing but them telling me not to worry isn't going to help. I have been a nervous wreck heading in or out of home and losing sleep over it. I went a long route to work for a few days then attempted to go my usual way and just couldn't do it. Any ideas on steps I could take? I doubt the police would give me an indication of where he lives but I'd like to have an idea of which side of me he lives so I can avoid it for a while where I can or be more vigilant. I asked in my nearest newsagents if they recognised him and unfortunatley he said he's been in a few times. I thought about anonymously posting his picture on some local facebook groups to see if he's know in a particular area but not sure if that is a good idea.
