Pair charged over drug supply

A man and a woman have been charged over an alleged drug supply ring in Sydney after the police raided homes seizing cash, drugs and Eftpos machines.

Four homes in Sydney's west and China Town were raided by police squads on Tuesday where thousands of dollars, two Eftpos machines, a taser and drugs including methylamphetamine were found, police say.

A 40-year-old man and a 33-year-old woman are due to face Sydney courts on Wednesday charged with drug offences and being involved in a criminal group.
