A man fed up with having £5,000 of tools raided from his van over the last two years has wired the door handles to a 1,000 volt current.
Ray Talor has also added a 120dB siren, two sound bombs and a strobe light to his Citroen Dispatch - alongside a sign warning thieves of the shock device.
Electrician Ray Taylor, 61, r told The Sun : "They'll get a zap." He added: "It's solved all my problems, so I can sleep easy.
"The shock isn't going to do any lasting damage but it will make you jump a bit."
Mr Taylor has connected a modified fly-zapper to his van and is now charging other people £380 to fit similar devices to their vehicles.
He says police have told him the device can be used so long as there is a sign on the van which clearly states it is electrified.
But Mr Taylor's local force, West Midlands Police, say they cannot condone his tactics.
Mr Talor has placed a sign which reads: 'Danger Live Terminals' under the handle - the only part of the van to be electrified.
