I got this from a neighbour just around the corner from me....
Hi Joan, hope your Xmas was a good one. Just wanted to let you know there have been 2 senseless attacks on neighbours of ours in the last few days, one a young mother in the passage at the side of our house has head injuries, the other a man walking his dog <other side of main road> was knocked to the ground, breaking his ankle - he saw his attackers high-five as he lay on the pavement. Both victims are frightened to share information on social media for fear of reprisals & the police have asked people locally to spread the information personally, not on social media, so local people can be aware & stay safe. Maybe you could let neighbours on <road> know? The attackers seen by the male victim were 4 black youths on powered scooters who have been seen recently around <junction>
So, that's great. I hope I don't become reflexively racist; young black men on scooters are pretty common. I am happy to say so far I have only twitched at passing scooters, not passing black youths.
If it's not obvious, I live in a generally safe area, so this unusual.
