Hunt For Missing Northampton Man
Officers are growing increasingly concerned about a 41 year-old man from Hunsbury in Northampton, who has not been seen for several days.
Miroslav Koucky has not been seen since he left his home near Butts Road on or around January 2.
He is eastern European, about 6ft 2in and it is believed he now has facial hair.
It is not known what he was wearing when he went missing.
Mr Koucky, or anyone who knows where he is, should call Northamptonshire Police on 101.
