A 22-year-old man has been charged with five counts of 'being concerned in the supply of class A drugs' and a number of motoring offences in Belfast.
The individual was arrested in the city centre on Thursday by detectives investigating the supply of heroin.
He is expected to appear at Belfast Magistrates court on Saturday.
Detective Inspector Pete Mullan said: "We are committed to tackling the supply of drugs into Belfast and other towns and cities across Northern Ireland.
"We continue to identify opportunities to disrupt the trade of drug dealers, to remove harmful drugs from the streets, identify offenders and bring them before the courts.
"Anyone with information on the sale and supply of drugs should feel confident about bringing that information to us. Police can be contacted on 101, or information can be given anonymously to the Crimestoppers charity on 0800 555 111."
