A Hampshire teenager who used an improvised explosive device (IED) to blow up a neighbour's car has been jailed for seven years.
Robert White, 19, put the bomb under a car owned by neighbours of his aunt and uncle in Bishopstoke, near Eastleigh.
White, from Truro Rise, Bishopstoke, appearing at Southampton Crown Court, had denied causing the explosion.
Judge Peter Ralls QC ordered White to be placed under extended licence for five years on his release.
Earlier the court heard that a row had broken out between White's aunt and uncle and their neighbours over a fence panel which had blown over in high winds.
White had created the device, similar to those seen in Afghanistan and Iraq, using a scaffold pipe welded shut with powder inside, believed to be from fireworks.
The force of the blast sent shrapnel more than 30m (98ft) and caused substantial damage to the Vauxhall Vectra, the court was told.
Sentencing White, the judge said the attack had been "premeditated and carefully planned" and could have caused serious injury or death if anyone had been near the explosion.
He said the case had been "bizarre" and said White had an unhealthy interest in guns and explosives and was a danger to the public.
He said: "I have no doubt you were fully aware of the very serious effect that such an explosion would have."
