Northampton missing person Keith Gregory has been found in London after going missing in November – in the east wing of the National Portrait Gallery, slashing a famous Gainsborough painting with a screwdriver.

We're still trying to find Keith Gregory, believed missing in London - have you seen him?

He was believed to be in London after being spotted on CCTV at Euston on the day he vanished, but it's unclear what happened to him in the intervening months.

Was wandering with a friend through the gallery yesterday, when one of the staff shouted at everyone to move aside.

An older man, surrounded by about 6-8 staff, was quickly taken past us.
