One of 19 arrests in dawn raids yesterday.
Four people had been charged in relation to the raids last night with more charges expected.
A Croom man was among 19 people arrested in dawn raids throughout Sydney and the Illawarra yesterday.
The 48-year-old was taken into custody as police searched his rural property and allegedly discovered a stun gun.
Police also raided properties in Warilla and Kiama but made no arrests in relation to those searches.

In what is being hailed one of the biggest firearm and drug operations in NSW history, a combined 350 officers executed 30 warrants across properties throughout Sydney and the South Coast as part of Strike Force Alistair.
It was a joint operation between police and the NSW Crime Commission, targeting organised crime in the state.
Police allegedly seized drugs, firearms, a hand grenade, a ballistic vest and around $500,000 in counterfeit cash during these raids.
They were targeting senior members of the Hells Angels, Comancheros and Rebels, as well as Asian and Balkan crime gangs.
Hells Angels boss Felix Lyle was one of four people to be charged so far as a result of yesterday's arrests.
Police were expected to lay more charges against individuals overnight.
NSW Premier Barry O'Farrell yesterday told Parliament the operation was "one of the biggest firearm and drug operations in the history of this state".
He said about 30 people would be charged with a raft of serious offences, some of which carry sentences of life imprisonment.
"This is the result of terrific work by the NSW police in targeting organised crime, drug supply and illegal weapons," the Premier said during question time.
Three other men - aged 35, 33 and 25 - were charged with offences relating to the supply of a commercial quantity of prohibited drugs.
Police said the raids came after a number of arrests three weeks ago over a conspiracy to import 400 kilograms of amphetamines, also as a result of Strike Force Alistair.
Detective Superintendent Mick Plotecki said that the charges would relate to commercial drugs supply, firearms offences, the provision of explosives and counterfeiting of cash.
He said a key component of the operation was "targeting those people that make these networks work".
"We're targeting particularly those people that go out and procure firearms and drugs, and also those that supply them."
Police Minister Michael Gallacher praised "the incredible efforts" of the police and the NSW Crime Commission.
He said everyone involved in the operation had "been relentless in smashing these criminal networks". AAP
