Police have seized more than four kilograms of amphetamines and a pill press after raids in Sydney's northwest.
Around 10.30 yesterday morning police spoke to a man who had been asleep in a car outside a factory unit in Anella Avenue at Castle Hill.
He appeared drug-affected - officers allege during a search of his vehicle they found $300,000 in a briefcase.
The 29-year-old was arrested, and search warrants carried out at the factory and his home in Rouse Hill.
During the raids police allegedly found a pill press and 4.6 kilograms of amphetamines worth $736,000.
Inspector David Miller says it's a surprising result.
“I must say it was very good police work from the police who attended… basically they spoke to a fellow for a short period of time, and after some suspicions arose they made further inquiries and ended up in a very, very good arrest.”
He's been charged with numerous offences including drug supply and will face court today.
