A 24-year-old church volunteer allegedly had sex in her car with an underage boy from her youth group, authorities said Monday.

Na Yun Choi of Northbrook was arrested Saturday night after police discovered her and the 15-year-old boy naked in a car at Wood Oaks Park in the north suburb, Cook County prosecutors said as Choi appeared in bond court.

Choi was charged with felony criminal sexual assault after she allegedly admitted having sex with the teen, prosecutors said.

If convicted, she faces up to 15 years in prison.

She was a youth leader at Agape Presbyterian Church in Prospect Heights, while the teen was a member of that group.

Choi attends the Korean-American church but is not a staffer, said a church official, who declined to comment further.

Police found Choi and the teen together about 11 p.m. Saturday while investigating a darkened car in a lot at the closed park.

Choi’s bail was set at $15,000.
