Two men from Sydney were charged with illegal possession of pharmaceutical drugs in Corrimal on Thursday afternoon.
Wollongong police inspector Darren Brown said police were called to a pharmacy near the Princes Highway following reports of two men, aged 49 and 36, acting suspiciously about 6pm.
He said when police arrived, one of the men allegedly ran.
Both were taken back to Wollongong Police Station where they were charged.
They will appear in court in January 2014.
