Can't find where I saw that now. Unless a crime has been witnessed, I'd phone 101. I did it one night after seeing mopeds going up and down quiet roads by my house, looking in all the parked car windows. But I was on the phone for 35 minutes with hold music so I gave up and hung up.
I was told to politely bugger off and call 101 after I was attacked in an attempted theft. Waited ages then hung up as well. This was a crime as well. Apparently, if not in immediate danger, it goes to 101. Go figure.
