The Lancaster County Sheriff's Office says on Tuesday of this week, between 4:30 p.m. and 10:30 p.m., a pick up owned by the department was left unattended in a Lincoln parking lot in the 600 Block of N. 48th Street, between Vine and R Streets.

The body armor has pouches that contained two loaded "Smith and Wesson" extended pistol magazines; one 23 round, and one 17 round, 40 rounds of 9mm ammunition, and an "Atlantic Signal" portable radio microphone.
There were no signs of forced entry.
Anyone with information about this equipment is encouraged to contact the Lancaster County Sheriff's Office at 402 - 441 - 6500 or Crime Stoppers at 402 - 475 - 3600.
