Carjacking suspect, Oct. 23, 2016.

DETROIT, MI -- Detroit police are looking for a 40-year-old woman they say carjacked a 74-year-old woman who was nice enough to give the suspect a ride when she asked.

The suspect approached the senior and asked for a lift as the victim exited McDougall Market on Detroit's east side about 10 a.m. Sunday.

"As the victim and the female suspect were heading east on Canfield towards Moran, the victim turned to look at the suspect she produced a weapon, pointed in her direction and advised her that she was being robbed," police said in a statement Monday. "The victim then exited the vehicle and the suspect fled the location in the victim's vehicle."

The suspect took the woman's four-door, 1997 green Buick Century, license plate no. CHG 1231. The suspect is described as a 40-year-old, 5-foot-8, 225-pound, dark-complected black woman with a large build and short, curly, brown hair.
