Police have discovered cannabis with a value of approximately £20,000 following a search in Newcastle town centre on Thursday.
The discovery was made by police carrying out inquires following an incident at a house in the area at approximately 1pm.
Three males, aged 17, 21 and 44, were arrested in connection with the incident. All three were subsequently released on police bail pending further inquiries.
The 21-year-old male has been charged with assault on police and is expected to appear before Downpatrick Magistrates Court later this month.
As is normal procedure, all charges will be reviewed by the PPS.
