Nebraska authorities have arrested a 31-year-old man who they say had sexual contact with two 15-year-old girls. 

Lincoln police arrested Adam Brunswick this week on two counts of first-degree sexual assault and child enticement. It's unclear if he's been charged. 

Under Nebraska law, people 19 and over cannot have sexual contact with people under 16.

Police say he met the girls through an online dating website and the three met in 2013 at Ballard Park in Lincoln. They say the girls performed sex acts  in exchange for cigarettes. 

One of the girls told her mother, who called police.
