On a local discussion forum, a Busher writes thus:
My daughter was mugged at 5:30am this morning on Percy Road on her way to work. The guy was on a bicycle, black, middle aged, thin and wore a hoody. Anyone see anything or anyone fitting this description, go to the police as the next person he mugs (or worse)could be you or one of your children.
I hope she is OK. Someone I know who stores his kids bikes in a shed had that broken into last week and one of the bikes stolen. When he reported it to the local police they told him that many bikes are now taken in order to commit this sort of crime, on a bike.
Erconwald Road in East Acton actually has a sign warning of mobile thefts being carried out by thieves on bikes as well.
Keep your wits about you.
