ASX-listed DroneShield, the maker of a gun to turn back unwanted drones, has gone into a trading halt.
The company says it made an announcement about a proposed capital raising.
Its shares last traded at $0.23.
The company uses acoustic recognition to detect drones and warn of their approach from up to kilometre away.
Its DroneGun, using jamming technology, sends the offending drone straight back to its owner.
