Police Helicopter

We had family visitors this morning and sat in the garden with our coats on; it was rather cold; then it rained.
 
This afternoon I had a Zoom meeting and I could hear a helicopter circling overhead. As I was not hosting the meeting, I went downstairs to see what was happening. It was a police helicopter and I managed to get today’s blip. It was moving away from me quite fast so it is not as sharp as I would like. I presume it was looking for something or someone; it eventually headed of towards the M11
   
The temperature today was eleven degrees Celsius at GMT noon.
