A live-in nanny was charged Thursday morning with third-degree larceny after police said she stole more than $12,000 worth of jewelry from the woman who employs her.

The employer made an unexpected visit to her Castle Avenue residence around 9 a.m. and told police that she saw 23-year-old Bridgeport resident Abigail Palmer taking jewelry from her bedroom closet.

Palmer fled on foot when she heard her employer calling police, according to Lt. Jim Perez, a Fairfield police spokesman.

Officer John Moran found Palmer about four blocks away, police said.

The five most expensive items of jewelry that were reported taken include: a Rolex watch worth $3,500, a gold coin ring valued at $3,000, a diamond earring set worth $3,000, a pair of earrings estimated at $1,500, and hoop earrings valued at $1,000.

Information on Palmer's bond and court date was not immediately available.
