Maricopa County Sheriff Joe Arpaio is bringing his crime-suppression sweep to Mesa on Thursday but hasn't provided details about the operation to Mesa police, Chief George Gascón said.

Mesa received the two-day notice in a hand-delivered letter Tuesday.

"It doesn't tell us when or where," Gascón said. "We are currently working with the sheriff's personnel to get some further information and how many days the operation will be." MORE
