Six men have been charged following the seizure of a substantial quantity of illegal drugs in Portstewart.
The haul of ecstasy on Friday was estimated to have a street value of half a million pounds.
The six men, aged 20 to 26, have been charged with a number of offences including possession of Class A drugs with intent to supply, and conspiracy to supply Class A drugs.
They are expected to appear before Coleraine Magistrates Court on Monday.
A 35-year-old man who also arrested during the police operation has been released unconditionally.
