Operation Jemlock officers stopped and searched three men in a vehicle on Gipton Wood Road on January 19.
Officers discovered controlled drugs.
A house search uncovered more drugs and a baton.
All of the items were seized by officers.
The men were arrested for supply offences, police said.
A suspect has now been charged.
Operation Jemlock was launched in April 2019 in a bid to tackle serious violent crime in the region.
Earlier this year, Superintendent Damon Solley who leads Operation Jemlock said: "Operation Jemlock has used the extra funding provided by the Home Office to place dedicated officers working extra shifts into key areas of West Yorkshire.
"Through specific intelligence led deployments and working alongside their district colleagues on patrol, neighbourhood and investigation teams, they have achieved outstanding results in the first year.
"Operation Jemlock has been at the forefront of our collective effort to tackle serious violence but the whole organisation has got behind it to make a real difference.
"The task now is to make sure we continue the hard work to reduce this type of crime as much as we possibly can and we are determined to do this.
"I am extremely proud of the officers and staff who have delivered this but there is no complacency. It is a tough job to tackle this crime type and reduce it.
"We will not let up in our determination to continue making the people of West Yorkshire safer."
