Two men have been arrested on suspicion of murder after a pensioner was bludgeoned to death in his home last week.
The suspects, both aged 36, remain in custody after police swooped on land off Tenterden Road, Golford, in the early hours of this morning.
The raid in the tiny village, near Cranbrook, follows the brutal killing of 73-year-old Roy Blackman who was found dead in his Headcorn Road bungalow, near Biddenden, last Monday morning.

Police have been removing items from the site all morning.
Officers have scaled back their presence but nine vehicles remain.
Last Wednesday a 49-year-old man was also arrested on suspicion of murder. He has been bailed, pending further inquiries, until Thursday, April 28.
Police descended on the abandoned Valdene Business Park, on Headcorn Road, near Sutton Valence, on Thursday morning.
Officers remained at the scene, six miles from Mr Blackman's homes, for most of the day and were seen taking away a number of items.
