Two teens and a 12-year-old girl are suspected of hitting a Good Samaritan in the head with a hammer and stealing her car.

The incident happened early Saturday in Colorado Springs, according to the police department’s crime blotter.

The victim, a 35-year-old woman, was entering a grocery store about 1 a.m. when she was approached by three juveniles, police said.

The trio told her they were stranded and needed a ride home. The woman agreed to give them a ride after she finished her shopping.

When the woman left the store, the boy and two girls were waiting outside. She gave them a ride to the the Winfield Apartments in the 5400 block of Grantsville Grove, police said.

The trio talked the woman into coming to their apartment to tell their parents that they had indeed been stranded.

The woman was led behind a building to a grassy area and struck on the head twice. She fell to the ground and was kicked several times.

“The victim was told to ‘stay on the ground or be killed,’ ” the blotter said. The suspects “forcibly” stole the woman’s car keys and drove off in the 2004 Honda Accord Coupe.

The victim contacted a resident at the apartment complex who called police.

A police officer spotted the car about one mile from the assault scene and stopped it at Charlotte Parkway and Anna Lee Way.

A 17-year-old boy, a 14-year-old girl and a 12-year-girl were taken into custody and held on suspicion of aggravated robbery and assault.

The boy was in possession of a hammer, which investigators believe was used in the assault.

The victim was treated for her injuries at a local hospital and released.
