Police fired a Taser at a 72-year-old man suspected of causing criminal damage in a Cornish village.
Devon and Cornwall police said officers discharged the Taser at the man in the bedroom of a house in St Day, near Redruth.
They had been called to the village after a 999 caller on Sunday afternoon alleged a man armed with a knife and hammer had threatened to "smash up" a car.
A police spokesman said: "A 72-year-old man within the property, who is believed to have had access to a number of weapons and firearms, refused to come out of the property.
"Firearms officers and a negotiator attended the property. Taser was deployed and the man was arrested at the scene for criminal damage. No one was injured during the incident."
It is understood that though the Taser was fired, the shot missed. The man remained in police custody on Monday.
