A 68-year-old woman has been arrested, accused of running a drug-dealing business out of her home in Sydney’s south.

Last month, Operation Viper detectives began investigating a suspected drug operation being run out of a home on Lyle Street at Hurstville.

At about midday yesterday, police moved in with the Dog Squad and arrested a 68-year-old woman.

After searching the home, officers found cannabis, ice, a revolver, taser, drug scales, and mobile phones.

The woman has been charged with multiple counts of supplying and possessing drugs and an unauthorised pistol among other offences.

She has been refused bail to appear in court today.
