Police have issued pictures of drugs seized in raids across Huddersfield this week.
Officers carried out a planned three-day operation to target suspected dealers throughout the town.
Kirklees CID said that drugs worth £140,000 were seized including £134,000-worth of class A drugs, much of it believed to be cocaine.
Cannabis plants were also found.
Police said they began gathering intelligence from the public in June and this week’s raids were the culmination of detailed investigations.
Detectives said the drugs trade was often linked to gun crime and some of the arrests were also connected to “recent firearms incidents” in Huddersfield.
Det Chief Insp Tony Nicholson, of Kirklees CID, warned dealers that police would not tolerate drugs on the streets and told them: “We will come for you.”
He added: “This was an intelligence led operation and it is important that we work with our communities and partners to identify, arrest and convict anyone who is involved in any kind of crime that involves drugs or firearms.”
Anyone with information on drug dealing or gun crime offences should contact Kirklees CID on 101 or Crimestoppers, anonymously, on 0800 555 111.
