Northamptonshire Police are continuing to try and trace a man missing from Northampton.

Mr Gregory was seen arriving at Euston Train Station shortly after going missing last Monday.
He has not taken medication with him and is believed to be vulnerable.
A spokesman for Northamptonshire Police said: “We are continuing to appeal for the public’s help in tracing missing man Keith Gregory, who we believe is in London.
He has links to London, specifically the Brick Lane and Golders Green areas and it is believed that he may have travelled to those areas.
We are appealing for people to let us know if they have seen him in the last week.”
Keith, pictured, is white, 6ft 2ins and was wearing a navy shirt and black trousers when he was last seen.
People are advised not to approach Mr Gregory directly but to call police immediately on 999.
