Four people were arrested and several weapons seized during a CAT operation in Jackson Friday.

The Jackson Police Department’s Criminal Apprehension Team conducted an operation Friday evening. Several weapons were found, including a ballistic vest, which police said contains body armor and is normally used in the military, or by law enforcement during specific special events.

Since January, the CAT operation has made 88 arrests and seized 50 handguns, 14 assault rifles and one shotgun. The team has also recovered stolen vehicles, including some from other states.
