Police in East Devon are warning the public about the potential danger from a Taser cartridge that was mislaid by a patrol officer on Tuesday night.
Police said there has been no previous reported incidents in the force area of a Taser cartridge being discharged without being attached to the Taser unit which supplies the electrical charge.
The cartridge contains probes on wires which extend when the device is discharged.
The probes could be inadvertently discharged by a build-up of static if picked up or handled.
Although the potential danger to the public is very low police advise that if found the cartridge should not be tampered with and handed in to the police.
The cartridge is described as being black in colour measuring 2inch x 1 ½inch with a serial number C31017NX4.
Police ask that if anyone finds the missing cartridge that they either contact police on 101 or hand it in at their nearest police station.
