The 47-year-old was arrested at about 9.50am yesterday in a planned operation in a car park on the corner of Botany Road and McEvoy Street in Waterloo.

Police used a Taser during the arrest, after which the man was treated by paramedics and taken to hospital.

Officers then carried out a search warrant at a premises on George Street, Waterloo, where they allegedly seized 14 empty vape bottles, 13 pen and marker bodies, wires, switches, USB cords, and power transformers.

Investigators will allege that these items were used in the manufacture of the prohibited devices.

Police also allegedly seized six complete stun devices, of which they will claim five were disguised as vapes and one as a permanent marker.

The arrested man has since been charged with multiple offences related to the making and selling of prohibited weapons.

He was refused bail and will appear in court today.
