The West Norfolk farmer Tony Martin, who shot dead a teenage burglar in 1999, is believed to have been arrested by police in Wisbech on suspicion of possession of an illegal firearm.
Martin, 71, served three years in prison for shooting dead Fred Barras, 16, at his home in Emneth Hungate, Norfolk, in 1999. He was initially found guilty of murder but this was reduced to manslaughter on appeal.
Police finished their search of the property later the same day. Mr Martin was released on police bail pending further enquiries.
A police spokesman said: “The man, who was arrested on suspicion of possession of an illegal firearm, has been released on police bail until late February 2016.”
Mr Martin was living alone at his farmhouse in Emneth Hungate, Norfolk, nicknamed Bleak House, when he caught Brendon Fearon, then 29, and Mr Barras, 16, inside. He fired his shotgun three times towards the intruders, killing Barras.
The case provoked a national debate about the measures homeowners can take to defend their property.
