Yesterday at about 3.30pm I noticed a man trying to get through our security door. He was trying one key after the other so I asked him what number he wanted and he said he lived at No 14. I told him our section only has numbers one to six. He said no I live here.

After a while he gave up and said it was a mistake. He had a small rucksack on his back which might have contained burglary tools. He is a thin white man aged about 40 and about 5ft 7" tall. His hair is black & he has a moustache. He was wearing a flat cloth cap & a thick sweater but had no coat on.
