I have just had a visit from a man with a woman and a young child in a tatty old Nissan 2.8 white van Reg No T 2556 U with VERDE SL Pinturas on the side asking for scrap metal. He asked my neighbours for batteries. Looked very undesirable to me.
So I politely told them to go away  ;)
This was in Bitem area in the middle of the morning.
Be alert
