Just last week, police officers made 121 arrests and seized various weapons including knives and a BB gun as part of the Operation Jemlock operation.
Operation Jemlock was launched in April 2019 in a bid to tackle serious violent crime in the region.
The 121 arrests bring the total made by Operation Jemlock officers to 4438, with more than 545 weapons having been recovered since the operation began.
West Yorkshire Police tweeted: "Our colleagues at @WYP_OpJemlock never stop.
"Last week they made 121 arrests (4438 total) and seized various weapons including knives and a BB gun.
"In helping to keep the communities of West Yorkshire safe the team has now recovered more than 545 weapons."
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."
