A 3-day effort between the Oakland County Sheriff’s Office and the U.S. Marshal’s Office in Detroit resulted in the arrests of 36 alleged violent criminals last week — more than one-third of the approximately 100 sought in the sweep, Sheriff Mike Bouchard said Monday.

Dubbed “Operation Egg Hunt,” it was part of an ongoing partnership between the two law enforcement agencies, Bouchard said.

Speaking at a news conference Monday afternoon, Bouchard said: “It’s critically important we work together. Criminals don’t recognize boundaries, so we have to work across boundaries…to find and track individuals that are wanted for violent crimes. And that’s what this operation was focused on.”

Those targeted had outstanding felony warrants “or a history including violent criminal activity — sexual assault, kidnapping, robbery, gunshots, narcotics, sex offenders — things like that,” Bouchard said. Of the 36 nabbed, 10 are sex offenders, he said.

An additional three alleged offenders “heard we were looking for them and gave themselves up,” he added.

Others were cleared from the list after it was determined they had died or for other reasons, he said.

Joining Bouchard for the news conference was Chief Deputy U.S. Marshal Jimmy Allen.

“Last week’s multi-agency operation displays our commitment to public safety, rule of law and joint-agency investigations,” Allen said. “Our longstanding partnership with the Oakland County Sheriff’s Office and many other great agencies in metro Detroit has been an invaluable tool to prevent and deter criminal behavior in our communities.”

Bouchard said “a small percentage of people (are responsible for ) a large percentage of the crime, especially violent crime” — as evidenced by criminal justice studies.

“If we can take them off the streets it makes communities immeasurable safer,” he said, adding that Pontiac is one community where such success has been seen due to cooperation among law enforcement agencies.
